Based on these data, which is true of the world population? A. The number of people added to the population yearly is increasing
B. The population size is getting smaller
C. The population is growing younger
D. The median age of the population is decreasing

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.
