Okay, i'm going to answer this question.
00:01
Let's talk about how do you make my equilibrium.
00:04
This is a population of turtles is found where dark shells are completely recessive to light shells.
00:10
So, let's have, oh, well, they are telling us that this is the dominant allel and this is a recessive allele.
00:14
So this recessive allele is for dark cells, dark shells, and this dominant a is for light shells.
00:27
Light shells allel and the dark shells allele.
00:29
In your survey you captured both dark -shelled turtles that are, well in this case, you're going to have, oh well, first, you're going to have the following genotypes and phenotypes.
00:45
Homocygous dominant and heterocybos, both are going to code for light shells while the homozygos excessive is going to cause for dark shells.
01:00
So practically for homozygos excessive, you only have one possible genotype.
01:05
While for light shells you have either this or this.
01:08
So it says that you capture both dark shell turtles that are a 452 and light shell turtles that are 478.
01:22
So between these two genotypes they're going to have 478.
01:26
So if you get the total number, you're going to get 10, 12, 13, 8 and 9.
01:36
You have a total of 930.
01:39
It says what is the genotypic frequency of light shells individuals in this population? so remember that according to hartie wemberg, p plus q is equal to 1, where p is the frequency of alleles in this population that are dominant and q is the frequency of alleles in this population that are recessive.
01:56
Also p square plus 2pq plus q square is equal to 1, where p square is the frequency of alleles in in this population that are homozygous dominant.
02:06
2pq is the frequency of alleles in the population.
02:08
That are hydrosygos and qsquare is the frequency of individuals in this population that are homozygose.
02:14
So this is for alleles and this is for individuals.
02:18
It says, or it is asking us for the genotyping frequency of light shell individuals.
02:24
It means for this in the population.
02:26
So first in hardwomen equilibrium, when you have two alleles, the dominant and the recessive, you are going to work first with with the homozyrocessive because for the dominant trait, you have two genotypes.
02:38
So it's going to be very difficult to work only with these two.
02:42
Because you're going to have two variants here that are p and also q.
02:46
But for dark shell, for example, you have only q squared.
02:51
So this is only one variable.
02:52
So first with this, you have according to this, that homozyrogy excessive in the population are 452...
