In a human population of 100 people at a blood locus there are two alleles m and n. the observed genotype frequencies at this locus are f(mm) = 0.26, f(mn) = 0.35 and f(nn) = 0.39 what is the frequency of the n allele in this population ? do not assume hw equilibrium.

Which of the following factors would not contribute to allopatric speciation? a) a population becomes geographically isolated from the parent population. b) the separated population is small, and genetic drift occurs. c) the isolated population is exposed to different selection pressures than the ancestral population. d) different mutations begin to distinguish the gene pools of the separated populations. e) gene flow between the two populations is extensive.
