Which of the following is an incorrect statement about the regulation of populations?

A) The logistic equation reflects the effect of density independent factors, which can ultimately stabilize populations around the carrying capacity.

B) Density-independent factors have an increasingly greater effect as a population’s density increases.

C) High densities in a population may cause physiological changes that inhibit reproduction.

D) Because of the overlapping nature of population-regulating factors, it is often difficult to precisely determine their cause-and-effect relationships.

Consider a heritable autosomal disease with an incidence in the population of 1 per thousand. On average, individuals with the disease have 80% as many children as the population average. In answering the various parts of this question, assume that mating is random. Now assume that the mutation rate is zero, that the disease is recessive, and that the disease allele is maintained in the population by heterozygote advantage. Calculate the heterozygote advantage,
