Question

What is the mathematical expression for the genetic equilibrium for genes with two alleles? Is this statistical distribution the same as the statistical distribution of the respective phenotypes?

Answer 1

Considering p the frequency of one of the alleles and q the frequency of the other allele of a given gene in a population, this populace of people produces p gametes with the first allele for each q gamete containing the second allele. therefore, the probability of the formation of the homozygous genotype for the first allele is p2; the probability of the formation of the homozygous genotype for the second one allele is q2; and the possibility of the formation of the heterozygous genotype is p.q + q.p, that is, 2p.q.

Because the sum of those possibilities is always 1, the resulting mathematical expression is: p.p + 2p.q + q.q = 1.In simple, the number of genotypic paperwork isn't always same to the number of phenotypic bureaucracy, because dominance and different interactions among genes affect the manifestation of the phenotype
