Help! Hardy Weinberg Equilibrium + Allele Frequencies?
A simple Mendelian trait has two alleles, D and d. if a population is in hardy-weinberg equilibrium and is 49 percent homozygous dominant, what percentage is heterozygous. What are the allele frequencies in this population
If you know the allele frequencies for a particular gene in a population, can you calculate the genotypic frequencies for a population?

If fr(DD) = 0.49, then fr(D) = 0.7. Therefore, fr(d) = 0.3.
Fr(Dd) = 2(0.7)(0.3) = 0.42.
Yes. In this case, fr(DD) = 0.49, fr(Dd) = 0.42, and fr(dd) = 0.09
