The frequency of a slightly deleterious allele maintained at an equilibrium frequency by mutation-selection balance would be higher

A) if the mutation rate is high.
B) if the mutation rate is low.
C) if the selection coefficient is high.
D) if the population size is small.

Deleterious Allele

A version of a gene that, due to mutation, can result in a lower chance of survival or reproduction for an organism that carries it.

Mutation-Selection Balance

An equilibrium state between the introduction of new genetic mutations and the removal of maladaptive ones by natural selection.

Equilibrium Frequency

A stable frequency at which a genetic allele is maintained within a population without the influence of external forces, typically as a result of evolutionary pressures.
