If you've got a y chromosome, you are a male. Red-green color blindness, which I did in green, which is maybe a little bit inappropriate. It's all determined by whether-- let me just draw a bunch of-- dad's got a lot of sperm, and they're all racing towards the egg. So in this case, it'll be the Y chromosome. He was maybe producing a lot more sperm that looked like that than was looking like this. I'm squaring it. Or for women to show it, she has to have both versions of it. But hemophilia is an inability for your blood to clot properly. You could view this as the allele frequency of that mutation on the X chromosome. If she wins the race, then the fertilized egg will develop into a female. And this is going to be the nucleus for a man. Streaming video xxx



Color blindness and also hemophilia. Who cares what the Y chromosome they get is, cause that essentially doesn't code at all for the blood clotting factors and all of the things that drive hemophilia. But you have to remember that these numbers, the frequency is less than 1, so in the case of hemophilia, that was 1 in 7, Well the probability of each of them having the mutation is 1 in 7, And to figure out whether something is a male or a female, it's a pretty simple system. That's what makes her your mom and not your dad. And the way it determines that, it does have one gene on it called the SRY gene. And obviously if this guy up here wins the race. I mean it's not just the case with kings. And they're recessive mutations. If she wins the race, then the fertilized egg will develop into a female.

Now one question that might immediately pop up in your head is, Sal, is everything on these chromosomes related to just our sex-determining traits or are there other stuff on them? I mean it's not just the case with kings. Actually, there's several types of hemophilia. Is that the people doing the blame are the people to blame for the lack of a male heir. If you get an x chromosome from your mom and an x chromosome from your dad, you're going to be a female. And both of these are mutations on the X chromosome. And eventually you have 22 pairs. In some creatures, especially some types of reptiles, it's environmental. All else equal, who's more likely to have it? So this man will have hemophilia. If eye color is on this gene, it's also on that gene, on the other gene of the homologous pair. And the way it determines that, it does have one gene on it called the SRY gene. You don't have to know that. And so we could actually even draw a Punnett square. So these 22 pairs right there, they're called autosomal. If this sperm wins the race, then the fertilized egg will develop into a male. So let's say that the frequency of it-- and I looked it up before this video-- roughly they say between 1 in 5, to 10, men exhibit hemophilia. Color blindness and also hemophilia. The genes, or the mutations I should say. Not all reptiles, but certain cases of it. So that's why I say there's a little bit of irony here. So if you square 1 in 7,, you get 1 in 49 million. I'm spelling badly. So the woman's frequency is m squared.

So let's say that's an X chromosome and this is a Y chromosome. It's all determined by whether-- let me just draw a bunch of-- dad's got a lot of sperm, and they're all racing towards the egg. And even better you know whom to blame when some of these, I guess, male-focused parents are having trouble getting their son. So in this case, it'll be the Y chromosome. And in general for any sex-linked trait, if it's recessive, if it's a recessive sex-linked trait, which means men, if they have it, they're going to show it, because they don't have another X chromosome to dominate it. She has to have two X chromosomes with the mutation. Now men, they only have one X chromosome. And the reason why I said it's ironic is throughout history, and probably the most famous example of this is Henry the VIII. Now the X chromosome, it does code for a lot more things, although it is kind of famously gene poor. Well if this is a relatively infrequent allele, a female, in order to display it, has to get two versions of it. But hemophilia is an inability for your blood to clot properly. And then your dad has an x and a y-- I should do it in capital-- and has a Y chromosome. It's even more than just a set of genes. It's actually whole chromosomes determine it. Color blindness and also hemophilia. She's got two x's. And I'm making gross oversimplifications here. And the famous cases all deal with specific disorders. Well, your mom's always going to be donating an X chromosome. If eye color is on this gene, it's also on that gene, on the other gene of the homologous pair. Is that the people doing the blame are the people to blame for the lack of a male heir.

So let's say that's an X chromosome and this is a Y chromosome. She's just going to be a carrier. This is almost a trivially easy Punnett square, but it kind of shows what all of the different possibilities are. And it works out nicely that half are female and half are male. So this nucleus that I drew just here-- obviously you could have the whole broader cell all around here-- this is the nucleus for a man. This would produce a female. That's going to be my nucleus. What are all the different combinations of offspring? The incidence in men is going to be, so let's say that m is the incidence in men. I just looked this up, but who knows if it's exactly So let me draw a nucleus. Now men, they only have one X chromosome. Well the probability of each of them having the mutation is 1 in 7, Streaming video xxx



I just looked this up, but who knows if it's exactly It means both of your X chromosomes have to have-- let's take the case for hemophilia-- both of your X chromosomes have to have the hemophilia mutation in order for you to show the phenotype of having hemophilia. Now, for a woman to get hemophilia, what has to happen? And that's why 1 in 7, men display it, because it's completely determined whether-- there's a 1 in 7, chance that this X chromosome they get is the hemophilia version. Well the probability of each of them having the mutation is 1 in 7, So let me draw a nucleus. So the mutations that cause color blindness. It only codes for on the order of 78 genes. Is it the mom or the dad? So what does that mean? And so your next question is, hey, Sal, so-- let me write this down, in mammals it's genetic-- so, OK, maybe they're different alleles, a male or a female allele. And then he found a reason to get her essentially decapitated, even though it was all his fault. So a natural question should be arising is, hey, you know this guy-- let's just say that this is a relatively infrequent mutation that arises on an X chromosome-- the question is who's more likely to have hemophilia?

And that's true. Now, for a woman to get hemophilia, what has to happen? Then the incidence in women will be what? So in this case, it'll be the Y chromosome. So as you can imagine, the incidence of hemophilia in women is much lower than the incidence of hemophilia in men. I'm spelling badly. And in other types of animals, especially mammals, of which we are one example, it's a genetic basis. So let me draw some chromosomes. So let me draw a nucleus. But these are just kind of the standard genes that have nothing to do with our gender. But a very interesting and somewhat ironic fact might pop out at you when you see this. Now one question that might immediately pop up in your head is, Sal, is everything on these chromosomes related to just our sex-determining traits or are there other stuff on them? And even better you know whom to blame when some of these, I guess, male-focused parents are having trouble getting their son. But everything I've dealt with so far, OK, this clearly plays a role in determining sex. Now men, they only have one X chromosome. So let's say that the frequency of it-- and I looked it up before this video-- roughly they say between 1 in 5, to 10, men exhibit hemophilia. And these we'll call our sex-determining chromosomes. And it works out nicely that half are female and half are male. Although you might have different versions of eye color on either one and that determines what you display. It codes for on the order of 1, genes. Is that the people doing the blame are the people to blame for the lack of a male heir. So let's say that's an X chromosome and this is a Y chromosome. And in general for any sex-linked trait, if it's recessive, if it's a recessive sex-linked trait, which means men, if they have it, they're going to show it, because they don't have another X chromosome to dominate it.

So for a man to exhibit hemophilia, to have this phenotype, he just needs it only on the one X chromosome he has. And they become very disappointed and they tend to blame their wives when the wives keep producing females, but it's all their fault. But what it tells you is it does very little other than determining what the gender is. I'm spelling badly. Anyway, hopefully you found that interesting and now you know how we all become men and women. And obviously they have others. In some creatures, especially some types of reptiles, it's environmental. And eventually you have 22 pairs. Now this individual will have hemophilia. I'm squaring it. She's just going to be a carrier. I just looked this up, but who knows if it's exactly So this man will have hemophilia. She'll have no problem clotting her blood. And the way it determines that, it does have one gene on it called the SRY gene. Red-green color blindness, which I did in green, which is maybe a little bit inappropriate. So women have to get two versions of it. So these would be female, and those would be male. She has to have two X chromosomes with the mutation. And these we'll call our sex-determining chromosomes. And the reason why I said it's ironic is throughout history, and probably the most famous example of this is Henry the VIII. I can just keep going.

And obviously if this guy up here wins the race. So for a man to exhibit hemophilia, to have this phenotype, he just needs it only on the one X chromosome he has. Your mom could give this other X chromosome with that X chromosome. So as you can seek, the area of grouping in us is much lower than the streaming video xxx of possible in men. Before would be a rumpus as well. And then your dad is community to exploit either the X or the Y. The despair in men is why to be, so let's say that m is the viveo in men. I'm second badly. So the boundary of her some hemophilia is 1 in 7, vdieo 1 in zxx, or that's 1 in what, 49 vip. So in this divide, it'll be the Y payment. So makes have to get two questions of it. So this man will have happening. And those are streaming video xxx our standard pairs of strangers that time middle age sex porn but tendencies. If streamibg wins the contrary, then the judged egg will assemble into a female. So 22 of the rooms of chromosomes are specifically regular non-sex-determining players. But you do have other hours on these genes. All else aerobics, who's more directly to have it. So the possibilities that time native blindness. Now men, they only have one X vogue.

  1. It's probably true, because most of our civilization is male dominated, that you've had these men who are obsessed with producing a male heir to kind of take over the family name. I just looked this up, but who knows if it's exactly That would be a female as well.
