Explanation / Answer
Answer
According to the hardy-Weinberg equilibrium
1- Population size for breeding is very large.
2- There should bear random mating in the population
3- No mutation to change the allelic frequency
4- No change the population size change due to immigration. Or emigration
5- Natural selection should in the population
In a population allelic frequency and genotypic frequency remains constant.
Let us suppose Gene C has two allele; A denoted by P and a is denoted by Q
Then,
Allelic frequency is P + Q = 1
Genotypic Frequency is P2+ 2PQ + Q2 = 1
So, In a question another Gene A has 4 allele denoted by P,Q,R,S
Then,
Allelic frequency is P + Q + R + S = 1
Genotypic Frequency is (P + Q + R + S)2 = 1
P2 + 2PQ + Q2 + 2PR + 2QR + R2 + 2PS +2QS + 2RS + S2 = 1
In a question Gene B has 3 allele denoted by P,Q,R
Then,
Allelic frequency is P + Q + R = 1
Genotypic frequency is (P + Q + R)2 =1
P2 + 2PQ + Q2 + 2PR + 2QR + R2 = 1
General genotypic frequency calculation with the formula is n * n+1/2
Where n is number of allele.
