In order to answer this question, let's talk about inheritance.
00:06
It says for the following genetic problems, use the information provided here.
00:11
Food color in mice is determined by two persifoliles, the aguri, non -aguri, and black brown.
00:18
Aguri determines the presence of a sub apical yellow band on each hair that gives a black fruit, mouse, a gray, mousey color.
00:28
This is the wild type of aggris black.
00:30
Okay.
00:32
And non -aguri mice are a solid color black or dark brown.
00:37
Aguri is dominant over non -aguri and black is dominant over brown.
00:43
So in greciom, this is what you have.
00:44
When you have the dominant a, dominant b, you're going to have the wild type.
00:48
When you have dominant a and recessive b, you have cinnamon.
00:50
When you have b and dominant b, you have black.
00:52
And when you have both, you say, you have chocolate.
00:55
It says, a chocolate, it means like this mouse is crossed with a true breathing white mouse.
01:01
It means true breathing means homocycles.
01:06
So you're crossing with a true breathing, wild mouse, then it means a disease, both homocycles dominant like this.
01:13
So this is your cross.
01:14
And it says a diagram, the cross of the f1, of the f1s to provide the phenotype ratio in the f2 generation.
01:21
So from this cross, you're going to find that amids in general when you have two genes by mixing each of these, each of the alleles from the first gene with each of the alleles for the v -ging.
01:34
Okay, in this case, you have that the only possible gamut here is like this, and the only possible gamut here is like this.
01:40
So you'll cross them you're going to get that all the offspring are like this.
01:50
Okay.
01:52
Now, in order to make your dijk hybrid cross, you need to make this, or your f2, you need to make this cross, okay? like in your f1.
02:02
But you already know that from a dijkabre cross, you get the following phenotype ratio.
02:08
That is 9, 3, 3, 3, 3.
02:10
And one.
02:13
But in this case, they are asking us to fill, to make the panetta square.
02:17
So let's make your panetta square.
02:19
You get the gametes from each of these parents, but they're going to be the same gametes for both of them.
02:23
And you're going to get the following panel square.
02:26
This is the panel square that you're going to get.
02:28
Here you have the gametes.
02:29
These four are the gametes from this parent, and these four are the gametes from this parent...
