Genotype Frequency

The frequency that a particular allele arises within a species, for example the coding of hair colour, where there may be a genetic frequency of 0.2, meaning for every organism, 0.2 have blonde hair, i.e. 1 blonde for every 5 organisms.

mutation-selection balance

... population, natural selection eliminates it. In this case, p, the gene frequency of the lethal allele in the population, is equal to μ, the mutation ... the selection coefficient for those who have a homozygous affected genotype. N.B. √ is square root in case it's not visible. What I don't get ...

Re: Re:

... it seems as if F1 somehow defies the Hardy Weinberg equation by having genotype frequencies that one would not expect from the allele frequencies. ... (both of which achieved different equilibrium points) are mixed. Thus, Frequency of the resulting F1 AA genotype is not p^2, but p1 (of the 1st ...

Re:

This is turning out to be an interesting thread (I love mathematics). Frequency of AA = 0.6 x 0.2 = 0.12 Frequency of Aa = (0.6 x 0.8 ) + (0.4 ... it seems as if F1 somehow defies the Hardy Weinberg equation by having genotype frequencies that one would not expect from the allele frequencies. ...

Gene Frequency

... If a random sample of females from one population is crossed to a random sample of males from the other population, what would be the progeny genotype frequncies? If these progeny are then allowed to mate at random, what would be the expected gene and genotypic frequencies in the next generation? ...
