We're looking at a cross, and we have the parental generation.
00:05
So we've got, this is one parent, and we're crossing that with this other parent here.
00:17
We want the probability, but the f1 generation will have this.
00:22
How do we work this out? okay, so the way we're going to do this is to remember that each gene is inherited independently.
00:35
So that's very important because we can look at each gene independently.
00:41
So if we start with a, we have the two heterozygotes.
00:45
What happens when you get this? you get 25 % homozygous dominance, 25 % homozygous recessive, 50 % heterozygous.
00:54
So the chance of getting this would be 1 and 2.
00:58
If we look at this, we have the same heterozygot cross...
