Which of these is not a principle of natural selection? A. Organisms produce more offspring than can survive.

B. Some variations are helpful. Individuals with helpful variations survive and reproduce more than those without these variations.

C. The environment plays no role in adaptations

D. Over time, the offspring of individuals with helpful variations make up more of a population and eventually become a separate species.

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.
