Not that to answer this question, let's talk about inheritance.
00:03
It says gene a has three alleles.
00:05
You have this allele.
00:07
You have this allele and this allele.
00:10
And for gene b, you have this and this.
00:13
And for gene c, you have this and this.
00:16
Now, it says, in a course between two parents with one with genotype, that is heterocycles for this allele, heterocycle for b and heterocycles for c.
00:29
And the other parent has the heterocygose a, the homozygo versus b, and the heterozyglozyg c.
00:36
And they are asking you, how many different genotypes would we expect to obtain in total in the overall population? so in this case, first, let's make three monohary panace squares crossing this genotype with this genotype, the b with the b and the c with a c.
00:52
So you're going to have this with the heterocygousygos like this.
00:59
And you get heterocygos, heterocybo, heterocybo, heterocyb, and homozygot recessive.
01:07
For the heterocygoyles v with the homocybozygot greciative v, you have heterocygote, heterocyg, homocyg co, and homocygotezygotes, and homocygoycese, and for the heterocygotechitis c with the heterocyglocigo c, you have formalis dominole, heterocyg, heterocyg, heterocyg, and homozygous recessive.
01:24
Now, about the total number of genotypes.
01:28
In this case, what you have to do, we can make a branch diagram.
01:30
For example, in this case, you're going to have, they are not asking us for the proportions.
01:37
So let's just focus on genotypes.
01:40
You have this genotype.
01:45
You have also the heterocygose, and you have the homocybocegoceive too.
01:53
In this case, you only have heterocygotechose or homozygot successive.
01:57
So in this case, you have heterocygotechose.
02:02
Just make it like this, heterocygotechios and homozygibos excessive.
02:08
The same here.
02:14
And the same here.
02:18
Finally, you can get also homocygous dominozygos and homocygous and homocyglysis.
02:22
So you have here, this, this, this, the same here, the same here, the same here, and the same here...
