In order to answer this question, let's talk about inheritance.
00:03
It is, imagine you have just purchased a black stallion of a non -genotype.
00:07
You made him to a red mare and she delivers doing folds one red and one black.
00:14
Can you tell from these vessels how color is inherited, assuming that alternativeally of a single gene are involved? so in this case you're crossing a black.
00:23
So let's suppose that you have here the homozygots for black.
00:26
There's going to be black obviously.
00:28
And the red is going to be like this.
00:29
You get the red.
00:31
And the heterocygous, you don't know what is the genotype because because you don't know which alil is dominant and which one is possessive.
00:38
So you're crossing a black that is like this and a red that is also like this because you don't know which allele is dominant in which one is recessive.
00:51
And in the sense that you're producing one red and one black fold.
00:57
So let's suppose that black is dominant.
00:59
Okay, so if black is dominant, then this one is also black, and if you're crossing a black with a gate, then you can have the homocybo's dominant, or well, the heterozygos actually, like this, and the homocybo recessive.
01:14
So from this cross, you're going to get heterocybos, heterocygos, heterozygos, heterocyboes, homocybolysis, and homozygibos decisive.
01:23
So in this case, if black is dominant, you can get black off -bring and also get off -bring.
01:30
So this can, this actually fits with the information.
01:32
But let's see if there is another possibility.
01:35
Now let's suppose that gret is dominant.
01:41
So in this case, this is going to hold for gret.
01:44
So let's just change this like this.
01:47
Now, if you cross a black with a gret, the black, the only possibility is like this, and the grette can be homozygous dominant or heterocylus...
