1.) How does the Hardy-Weinberg provide a baseline for identifying how populations evolve, as a function of changes in their allele frequencies?

2.) Grey squirrels are predominate since they are camouflaged better than their black-coated relatives. Describe one physiological reason why concentrated populations of the black variant are commonly found in some northern city parks.
