(Biology Question) Crickets communicate with other crickets by chirping. Crickets who cannot make a sound are less likely to find a mate and reproduce. For this reason, there are few crickets that cannot make a sound. This is an example of — (It's not "C)" I already tried)
A) natural selection
B) selective breeding
C) learned behavior
D) genetic replication

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.
