Title: Hardy Weinberg/ Genetics: What will the frequency of the recessive allele be in 100 yrs? Post by: Juliakg1 on Sep 15, 2012 If no one with the recessive disease is allowed to reproduce for 100 years, what will be the frequency of the recessive allele? (Assume random mating and a generation time of 20 yrs)
q=0.005477 & p=0.9945 Am I right in thinking to use this equation --> q after "n" generations= (original q) / (1+ n generations x initial q) ? Title: Hardy Weinberg/ Genetics: What will the frequency of the recessive allele be in 100 yrs? Post by: BuhReddy on Sep 15, 2012 yes you are correct.
After one generation q' = q/1+q since the homozygous recessive is 100% selected against. Expanding this out over several generations, the equation reduces to qn=q/(1+(n*q)) |
