What does relative fitness have to do with the future gene pool?3.What is the main ecological unit that can evolve?4.If a population of Larkspur has 4 white flowers in a population of 112 individuals, and white is homozygous recessive, how many individuals in a population that has 672 wouldbe heterozygous? What is the frequency of the dominant allele? 5.A population consists of 100 individuals of the following genotypes:AAAaaa155035a) What is the frequency of the alleles?b) Is this population in HW equilibrium, or is it evolving? Explain.6.At the individual level why is energy efficiency important in natural selection?7.Why would the genetic composition of a single species located in two separate locations be different? Give five reasons.8.An ecologist surveys two populations of kangaroo rat, Diplodomys ordi. Each populationis separated by the Saskatchewan River into two subpopulations.
