A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the trait). Unlike most natural populations, this population is best characterized in which of the following ways?
a) there is a genetic equilibrium
b) there is gene flow
c) there is genetic drift
d) mutations occur
e) mating is nonrandom

Question

Sourav Pan · Answer
