In order to answer this question, let's talk about the inheritance.
00:03
If a population has three alleles at a locus, like the abo -blatt -type locus, and the elite frequencies are 0 .3, 0 .2, and 0 .5.
00:13
What is the frequency of homocygodes? so in this case, first, you have that p plus q plus r is equal to 1.
00:25
Okay? so the frequency for p is 0 .2.
00:29
The frequency for q is 0 .3, and the frequency for r is 0 .5.
00:35
Now, you also have that p -square.
00:37
I mean, if you square this value here, if you square this, you're going to get that.
00:45
P -square plus q -square plus r -square plus 2 p -q, plus 2 -pr, plus 2 -q -r, is equal to 1.
00:55
So in this case, p -square is the frequency for homocygot for this allele here.
01:01
Well, let's give an allele here.
01:04
Let's suppose this a allele, this is the b -a -allid, and this is the c -aid.
01:08
So in this case, p -square would be the frequency for homocycles for a, q -square for b, r -square for homo -sigures for c.
01:19
2 -p -q would be the frequency of heterocygol's.
01:22
P -q, it refers to a -n -b.
01:25
So you have the heterocytocytocos ab.
01:27
2 -p -r would be for a and c...
