Berlin: here are my answers. Q1: this example is not constent wiht the hardy-weinberg model because some people in the population cannot survive(not all the alleles able to pass to offsprings), reproduction is not radom because there is related-marrage which increase the mutation rate. Q2:a)0.051653, b)0.5971, c)0.35124 d) 0.227 and the frequency of mutant alleles is much higher then other population, e) this large discrepancy is due to ralated marrage( increasing the mutation rate) and Founder effect. The Fugate are isolated in a small island. Thus, a mutant allele in a person can cause a big genetic drift of the population that increasing the muntant allele frequency dramtically. Q3: the outside comunity will increase the frequency to muntant alleles and genetic variation because Fugates who have a high frequency of mutant allele are introduced into the comunity; while the population of kentuchy will decrease the mutant allel frequency not only new individuals with low mutant allele frequency are introduced into the population, people with mutant alleles leave the population. This is called gene flow. Q4: this selection is called stabilizing selection which the average weight genotype associated with NADH Diaphorase will be favoured. The consequence will be that the genetic variation and diversity decreased.
