Okay, in order to answer this question, let's talk about genotypes and phenotypes.
00:04
Remember that, for example, if you have this genotype here, in order to get the gametes for this genotype, or for this organism, for this parent, you have to mix this a with this a with this b, and then with this b, and the same for this small a.
00:19
Okay, so the following gametes that you can produce are going to be a b, a, b, a b, small a, b, and small a, b.
00:29
These are the following gametes, okay? so you have four possibilities, four possibilities, okay? so as you have four possibilities, then 100 % are going to be four.
00:42
And each of them is going to have, how many chances to be found? well, we just divide 100 by 4, and this is going to be 25%.
00:53
So there are 25 % chances to get each of them, 25%, 25%, 25%, 25%, and 25%.
01:02
So this question says, fill in the gamutin genotype probabilities and offering genotypes to complete jessica and tom's pandel square.
01:12
So this is, these are the gametes for this, for the father, and these are the gametes for the mother.
01:19
You have only two here.
01:20
So, if 100 is the total, then you just divide it by two and you're going to have 50%.
01:26
So the probability to get each of them is 0 .5 or 50%.
01:32
Remember that this percentage, so in order to convert this to a decimals, you just have to divide by 100, and you're going to get 0 .5.
01:41
Okay, so here you have 0 .5 and also here 0 .5.
01:47
And the same for the other parent.
01:54
But in this case, this parent has four gametes.
01:58
So the probability for each of them is going to be 25 or 0 .25, 0 .25, 0 .25, 0 .25, 0 .25, and 0...
