a) * Selection is favoring a beneficial recessive allele in the population on the left and a
beneficial dominant allele in the population on the right.
b) The selective coefficient is smaller in the population on the left than in the
population on the right.
c)" The graph on the left shows heterozygote advantage; the graph on the right shows
a beneficial dominant allele.
d) * The graph on the left shows genetic drift; the graph on the right shows natural
selection.
The graph on the left shows an unstable equilibrium; the graph on the right shows
a stable equilibrium.
