Old classification systems based on physical characteristics would most likely disagree with the relationship between which two animals in the tree?
crocodiles and insects
bats and humans
birds and bats
humans and crocodiles

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.
