Unformatted text preview: s in each population). You calculate that Fst = 0.4 between the two populations. What is the number of effective migrants per generation? What would you tell the National Park manager about whether there is one or two populations (effectively)? Nm = (1/Fst) – 1/4 = (1/0.4) – 1/4 = 1.5/4 = 0.375 migrants per generation. There is less than one migrant per generation, so these are two distinct pupfish populations. 4 7. What is the value of H (heterozygosity) for a population of pupfish in Hardy-Weinberg Equilibrium for a microsatellite locus that has 8 alleles and the following frequencies of homozygotes in the population: A1A1 = 0.01, A2A2 = 0.01, A3A3 = 0, A4A4 = 0.05, A5A5 = 0.07, A6A6 = 0.01, A7A7 = 0.02, A8A8 = 0.03? H =1 – frequency of homozygotes H =1 – 0.01 + 0.01 + 0 + 0.05 + 0.07 + 0.01 + 0.02 + 0.03 = 1 - 0.2 = 0.8...
