maximal birth rate = for every woman, there's at least one man she doesn't share a parent with or descend from and you can even strengthen the second constraint to just breeding is always within the same generation
Okay so apparently it's 42 unique protein coding genes, but only one (SRY) is used for sex determination, and it seems like the others serve functions related to sperm production
The Y chromosome mutates quicker than other chromosomes anyway tho, so initial diversity probably isn't as important
Yeah it looks like SRY is basically just a boolean flag that says "testicles please" and doesn't actually provide any information on how to be male
I hope it goes somewhere... is it substantial enough? I worry that reddit has too many users for the portion that care and go on strike to impact enough for reddit to actually care
@Simd you're going to have problems with inbreeding with less than like 100 people
@RydwolfPrograms there's actually a really cool mutation where the sry gene gets translocated onto X
So you can have female characteristics while being XY r male characteristics while being XX
I wonder what happens if a male with one normal X and one mutated X has a child with a female with one normal X and one mutated Y and their child has a mitated X with the SRY gene and a Y without sry
Viable or not?
Does Y have any useful genes apart from the male reproductive organ thing and nose hair or whatever?
Wait would having a normal X and a Y without sry be tge same as having only an X? Turners or whatever?
Unrelatedly, anyone here want to volunteer for a...study?
I think from what I read the non-SRY genes in the Y chromosome do some stuff relating to sperm production
Which would make sense
@user There're all sorts of cool intersex mutations
Apparently in animals which work pretty similarly to us, there have been documented cases of ones which have both functioning male and female genitalia...so they can self-fertilize
So theoretically it should be possible for a human to exist that could reproduce asexually
> The human Hairy Ears phenotype has traditionally been regarded as the only Y-linked heritable trait. Here, we use Y-chromosomal DNA binary-marker haplotyping to show that a cohort of southern Indian Hairy-Eared males carries Y chromosomes from many haplogroups of the Y-phylogeny, which, under a hypothesis of Y linkage, would require multiple independent mutations within a single population.
> We further show that there is no significant difference between the Y-haplogroup spectrum in Hairy-Eared males and that in a geographically matched control sample of unaffected males. The trait cannot, therefore, be Y-linked in southern Indians, and by extension, is unlikely to be so in any population.
Apparently the Y-linked ear hair mutation has been disproven
@user Wait so you mean your chromosomes don't determine what bathroom you use? TUCKER CARLSON LIED TO ME?
@user I don't think a mutated X chromosome with the SRY gene would be enough to be able to have children
Since the Y chromosome has genes coding for stuff relating to sperm production, and from what I understand there's at least one (ZFY) that, if missing, will cause immediate apoptosis of gametes
I suppose if the X and Y chromosomes are already doing translocation they could happen to mix in all of the genes necessary for sperm production, in which case the answer would probably be "they'd be a normal male" since the X with SRY would be like having both an X and a Y, and the Y without SRY would be like no chromosome at all? But gene expression could fuck that up
Teenage pregnancy, also known as adolescent pregnancy, is pregnancy in a female adolescent under the age of 20. This includes those who are legally considered adults in their country. The WHO defines adolescence as the period between the ages of 10 and 19 years. Pregnancy can occur with sexual intercourse after the start of ovulation, which can be before the first menstrual period (menarche) but usually occurs after the onset of periods. In healthy, well-nourished girls, the first period usually takes place around the age of 12.Pregnant teenagers face many of the same pregnancy related issues as...
@RydwolfPrograms No, I misremembered, apparently it's ear hair (or rather, there's one trait for extra hairy ears that's Y-linked (according to the very first Google search result I got))
Dannyu NDos corrected me later
Oh nvm I didn't read your later messages
@RydwolfPrograms Isn't self-fertilization different from asexual reproduction?
You're still having sex, it's just that you're having sex with yourself
@PlaceReporter99 There's a lot more than 3 of them
Apparently it's just 50, not 100, but still, you need more than 7
@Adám I was gonna say it'd mess with your education while you're just getting started with college and stuff, but I guess if you're just trying to repopulate the Earth then that's not really a factor
Also, most teenagers probably aren't qualified to raise a kid properly, but again, doesn't matter in this scenario
Unrelated, but it'd be nice if the government could provide free training to people who are about to be parents
Doesn't your brain not finish fully developing until you're around 25? Not that teenagers are brain-dead or something, but a child is a huge responsibility
@mousetail I don't know about you, but I do not remember being a preschooler at all, and by the time the child gets closer to their teen years, the teen parent is going to be an adult and will have forgotten about that
@mousetail Do the same to her when she starts going senile
Even if you are like 14 you are dealing a lot with children of all ages, at school and social situation etc. I don't have any reason to interact with kids anymore so I don't know how they work anymore
A couple years ago, I tried tutoring a third grader (my school district makes us get service learning hours by volunteering for stuff), and it went pretty poorly, couldn't really communicate with him at all
In fact, not even 16 year olds, back when I was about 8-10, I used to hang out with a bunch of other kids from the same apartment complex, and the older kids (who were 13, tops), had absolutely no idea how to get the younger kids (6-10) to cooperate
Eventually, they'd just make the younger kids sit out any games that were happening
I wish people had to take a test and get a license before they could have kids, but that's not feasible and a bad idea for multiple reasons :(
@user do you mean gen alpha? if so i’m not sure that’s the case
it’s definitely true that some are more lazy, but i’m not sure that’s the main result of all the iPad, roblox, kids youtube. the main trait i’ve noticed among kids (6-10) recently is an extreme desire to constantly be entertained
gonna sound like a boomer here but I totally agree; I think the main impact of all the social media and overstimulation is an inability to focus and extremely high gravitation to immediate/instant gratification and like you said, constant stimulation/entertainment
I think user was probably joking about the entire generation being lazy but I could be wrong lol.
for example, my cousin (9) is always asking his parents to use his iPad, and my godsister (8 at the time i believe?) took her mom’s credit card to buy robux. but i have seen kids who are 11 now that have matured significantly, i don’t think that generalization you made is accurate
@hyper-neutrino maybe, idk i don’t know what your sense’s of humor are that well
to be fair i am pretty late gen Z so i’m a bit biased, but it also means i know more gen alpha kids better. and i can say neither of the examples i mentioned are lazy, just very dependent on that instant gratification. tbh, i can relate to an extent, but not as much since i don’t use much social media
She said something along the lines of "do you like your job" and I was like "does anyone :p" with a little smile, and then she was like "well actually I do, I make $100k a year. That's the problem with your generation, you don't know how to make money."
But I find it so funny and bizarre that she seems to be expecting 17 year olds, still in high school, to be working full-time salaried jobs and like, climbing the ladder or whatever lol
I like how you can get such precise snapshots of peoples' personalities in the couple of minutes while you scan their groceries
The worst are probably the ones who think they're really good at reading people's emotions when they really aren't
Like obviously standing in one spot for five hours straight saying the same two sentences makes you pretty tired right...well y'all have no idea how many people mistake "tired" for "depressed" and like, randomly walk up to me and say shit like "are you okay" and how do you even respond to that
Had one middle-aged dude who was like "you're not very good at customer service", in a somewhat aggro tone. Like, out of nowhere. We talk back and forth for a sec, and he asks "if you don't like talking to people who do you have this job?" and I was like "...cause I gotta pay for college?" and he was like "wait really?" and that's when I realized just how disconnected some people are from the real world
unfortunately a lot of people are very out of touch with the state of the economy these days
back in their day they could get a good job with just a high school diploma unlike these days when you can't get shit without a degree, and that job would pay for their family with 5 kids as a sole breadwinner
@RydwolfPrograms Well, to be fair, she did have a counterexample to your blanket statement. :P (But I find it a bit odd that she seems to think that high salary => liking your job. It's entirely possible to make a lot of money working 80-hour weeks and be miserable.)
Interesting. I guess I don't use people's names if they just have a nametag, but I try to do so if they introduce themselves verbally (like waiters or people on the phone).
Like sometimes, especially since I live in the southern US, it really is people just trying to be friendly. But other times it feels much more like they're pointing out that I'm paid to serve them and not the other way around.
@user Personally, as an adult, I find it easier to interact with kids than with teenagers. Kids will come up to you and just start talking. Teenagers usually don't initiate, which leaves me worrying about whether they would want to talk to me at all, so then I just avoid them. :P
Puzzle: Say there are only 7 humans and they want to repopulate the Earth. How many women/men should there be to do this most quickly? The rule is no one can have a child with a descendant, a sibling or someone under 20.
It's not the actual inbreeding that causes inbreeding depression, it's the reduced gene pool. You can avoid having children with descendants and siblings all you want, that's not going to matter a few generations in.
In a meeting with some moderators last week, I committed to releasing the data sets from our initial studies around the efficacy and false positive rates of ChatGPT detectors to them. Tuesday afternoon, we did so. This post contains as much information from that discussion as we are able to share...
@RydwolfPrograms just read the TLDR and i don't buy it.
> If every GPT poster posted exactly three answers and were suspended within three weeks, this would imply a minimum GPT post rate of 330 answers per week on Stack Overflow; in practice, we would expect a significantly greater quantity. Measurements of GPT occurrences on the platform imply fewer than 100 GPT answers per week, in disagreement with this rate, implying the existence of many false positive detections.
While the data isn't of high quality and isn't hugely convincing (necessarily so; if there was an easy way to figure out if a post was genuinely from GPT, we'd be using it and the question would be moot), I think it does provide good justification for why SE would have taken the action they did
They shared this data with us mods on Tuesday (as they said), and the difference between what they shared to us for feedback, and what was just posted is not massive
This metric is not intended to measure anything at an individual level. SE's not stupid, they know people edit at different speeds or copy-paste from drafts in other editors. It does, however, make a lot of sense to me that per-site the rate at which drafts are saved would remain fairly constant, unless suddenly a new tool showed up from which people we copy-pasting from
I suppose I don't have all of the information then, but based on that which I have access to, SE's actions seem pretty reasonable and the strike seems pretty senseless
I will say, they aren't diametrically opposite stances (e.g. we were told to nuke anything that could even potentially be GPT). Rather, we can't share what the "very strict standard of evidence" is, but it is significantly different from what they claim in that post
I can see the air is dirtier than normal and it smells faintly of smoke sometimes, but fortunately it has not been too bad where I live; I've had no issues biking to and from school daily
the main issue it's made me face at the moment has been walking to and from subway stations, in the station it's not bad but i live about a ten minute walk away and its terrible
on an unrelated note: i have a list of tokens from a lexer that have information about token type, location, etc. but some of the tokens are in a separate list. how can i insert tokens from the other list into the main one at the correct positions? for some reason i'm struggling to figure this out
the only way i can think of is to have a for loop of every index in the source string and check if any token starts at that index, but i feel like this is overthinking it. maybe i'm wrong though, i'm going to start with this
in most cases it probably won't be too large, i'm just trying to implement a simple syntax highlighter for my language on its docs site but i'm too lazy to figure out textmate grammars
the problem is my lexer separates the comments from the rest of the tokens. but i think i'm just going to go through with my initial idea
ok it worky
the code is a bit inefficient but it doesn't matter since it's generated at build time for the static site
Any mods on? Can someone please have a word with that irritating little Kpop kid, or ban them, before I completely lose the rag with than and end up getting myself suspended?!
