In order to answer this question, let's talk about the hardy wemberg equilibrium.
00:04
Suppose 16 % of a salamal population has a short tail, and the short tail allele is possessive.
00:10
So in this case, when you have the homozygous dominant or the heterocygot, you're going to have long tails.
00:20
Suppose long tails, because they are not telling us the genotype for or the pharynoticotile, and the homozygousal adhesive is for short tail.
00:28
Short tails.
00:30
Now, it says, suppose 16 % of a cellatine for a small tail.
00:34
Salamander population has a short tail.
00:36
It means that 16 % of salamander have the homozygo decisive genotype.
00:42
Remember that p plus q is equal to 1, where p is a frequency of adiles in the population and q is a frequency of recessive adiles in the population.
00:51
You also have that p square plus 2pq plus q squared is equal to 1, where p square is the frequency of salamander with the homozygous dominant genotype, the same for 2pq but for heterocyg therogels and q squared is homozygo in this case, the frequency of short tail is 16%.
01:11
And this is for q squared, because q squared is a frequency of homocycle recessive, that is short tail in this case.
01:17
So it means that q squared is equal to 16 % is the same as 16 divided by 100, and this is equal to 0 .16...
