We have a question about the hardy -vine verb equations.
00:04
So before i even start, i'm going to write them out.
00:08
So i always find this helpful.
00:11
So these are the two equations we use.
00:14
First for the allele frequency, then for the genotype frequency.
00:19
Now we can actually have a look.
00:20
So the incidence of an autosomal recessive disorder is one in 3 ,500.
00:27
So that's going to be q squared.
00:29
It's one in the 3 ,500.
00:31
Now, what is the frequency of carriers? so we've been given the frequency of people who actually have the disorder.
00:38
We want the frequency of carriers, which are the heterozygotes.
00:43
So already i've taken the word problem and i've switched it into equations.
00:50
Because from this we can work out.
00:52
So we know what q squared is.
00:54
From this we can work out what q is...
