We have some allele frequencies.
00:02
The dominant is 0 .4, the recessive is not .6.
00:07
If the population is at hardy -weinberg equilibrium, what is the frequency of heterozygotes? okay, when you see hardy -winberg, you're almost certainly going to be using these two equations.
00:18
So they're worth writing out.
00:21
They look like this.
00:24
So these are the hardy -weinberg equations.
00:26
This top one is for allele frequency.
00:29
Every copy of the gene is one of these two alleles.
00:32
So if you add up their frequency, you'll get 100%.
00:35
And you can see this holds true.
00:37
60 % of the copies are recessive, 40 % are dominant.
00:42
This one is for genotype frequency...
