A population of laboratory rats in Hardy-Weinberg equilibrium displays a polymorphism for coat color controlled by two alleles at a single locus. The B allele codes for black coat colour and is completely dominant. There are 200 rats in the population: 32 are white and 168 are black. How many of the black rats are heterozygous (Bb) at the coat-color locus?

1. variations in a population of moths allow for some of its members to be able to adapt to environmental changes. the better adapted of the moths will be able to survive the change and thus prevail as the “fittest” of the species. (a) describe three mechanisms in which variation can occur within a species population. (b) explain which mechanism or mechanisms would be responsible for the survival of a population of peppered moths better than white moths in an environment affected by industrial soot. justify your answer.
