In order to answer this question, let's talk about the inheritance.
00:02
It says in humans, the elite for brown eye color is dominant to the which causes blue eye color.
00:08
So when you have the homozygos dominant or the heterogeneous eyeballs, you're going to get brown eyes.
00:15
And when you have the homozygos, which is if you're going to get blue eyes.
00:21
It says if a brown -eyed man whose father had blue eyes, so remember that one person in here is one alibi from each parent.
00:28
So in this case, you have a brown -eyed man.
00:30
So the genotype is like this, because the man can be used.
00:33
Homozygous dominant and heterocybozyg.
00:35
But it says that this man had a father who had or who has blue eyes.
00:40
It means the father is homozygous recessive.
00:43
So it means that this father can only transmit recessive alleles to this man.
00:47
So it means that this space here is going to be recessive.
00:52
And now this man married a brown -eyed woman.
00:55
So a brown -eyed woman is going to be like this because we don't know if she is homo -sigorous -lidilis.
01:00
And the first baby of this couple has blue eyes.
01:03
So if the first baby has blue eyes, it means that what we had said be came from one parent who was a baby came from the second parent.
01:13
So it means that this blank here is too.
01:15
It says, what is the genotype of a man and the genotype of the man is heterozygos? thing is the same is the genotype of the woman and the genetic of the woman is heterocyg also.
01:24
Question says, what is the expected genotype peak and phenotyping among all possible children? so let's make up on a square for this.
01:32
You have homocygous dominant, heterocygles, heterocygous and homocygous and homocygous and recessive.
01:37
So, when they ask you for the genotyping ratio, you have to focus on different genotypes that you get from this panel square...
