This population of 11 bugs, we want to know what is the frequency of each allele.
00:05
So based on the picture, we can see that there is one individual who is homozygous dominant.
00:11
There are nine who are heterozygous, and there is one who's homozygous recessive.
00:18
So from this, we're going to calculate the dominant allele and the recessive allele frequencies.
00:28
Now, when we look at the hardy -winberg equilibrium equation, there's two of them, but the one we need here is p plus q equals 1.
00:39
This is a representative of allele frequency.
00:42
It says that p, the frequency of the dominant allele, plus q, the frequency of the recessive allele, have to equal 1.
00:51
Meaning that the number of dominant alleles plus the number of recessive should equal 100%.
00:57
Because if there's only the dominant and recessive alleles, then that's all you have.
01:04
If you count them all, that should equal 100%.
01:06
So we're going to calculate these frequencies by looking at all of these genotypes that we're given so readily.
01:15
Because, for example, when i look at the dominant b allele, i'm going to see where all the dominant b allele exists...
