Can someone please help me with the following questions. Please provide an answer/explanation especially for the first three. ?. Suppose a population of flour beetles has 1,000 individuals. Normally the beetles are red; however, this population is polymorphic for a mutant autosomal body color, black, designated by bb. Red is dominant to black, so BB and Bb genotypes are red. Assume the population is at Hardy–Weinberg equilibrium, with equal frequencies of the two alleles. What would be the allele frequencies...
