Two populations of a species of frog live around the gulf of california. one population has a brown back, and lives on rocky islands with brown rocks and little vegetation. a second population lives on the mainland among the vegetation and has a back that is speckled with green and brown spots. if, after many generations, a reproductive isolating mechanism evolves, what type of speciation most likely occurred? a. sympatricb. postzygotic isolationc. habitat isolationd. allopatric

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
