Question

A locus with two alleles, B and b, affects the viability of seeds in a plant population. One-fifth of the BB seeds germinate and produce adult plants. One-sixth of the Bb seeds germinate and produce adult plants. One-tenth of the bb seeds germinate and produce adult plants. Fertility does not depend on the genotype at the B/b locus. If the frequency of B is 0.25 in one generation and the genotypes in that population of seeds are in HWE, what will be the frequency of B in the seeds in the next generation?

Explanation / Answer

The frequency of B allele in the next generation is the same 0.25, becuase the allele frequencies do not change for generations, which are in Hardy-weinberg equilibrium, but the gene frequencies do change.
