In order to answer this question, let's talk about inheritance.
00:03
It says the inheritance of color in domestic pyjones involved several genes.
00:08
The dominance hierarchy of three color allele is azureate, blue, black, and brown.
00:16
So this is going to be the hierarchy, okay? where this is going to be, red, this is going to be blue black, and this one is going to be brown.
00:37
So this is the hierarchy of the alleleys.
00:39
Then it says these colors are targeted on the z -sex chromosome.
00:45
Unlike humans, female pigeons have two different sex chromosomes, z and w.
00:49
So females are going to be in w and males have two of the same kind of sex chromosomes.
00:59
It means females are going to be like this.
01:03
Now it says a heterocygos, a blue -black male pigeon.
01:08
A heterosigous blue -black pigeon.
01:11
Okay, so as it is a male, it is going to be this, like this.
01:17
Okay.
01:18
And also it is hittorocytos blue black.
01:20
It means it is, it has this all this alleles here.
01:25
And as it is hittrocygos, then the second alil is going to be like this, a brown alil.
01:30
It cannot be, this second alil cannot be this allele here because this is dominant over this allele...
