Natural selection acts on populations of living things, usually through a specific trait. which statement must be true about that trait? a) the trait is passed on genetically to the next generation. b) the trait is resistant to mutations. c) the trait is the same for all organisms. d) all forms of the trait have the same impact on survival.

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.
