Which statement best describes the relationship between an allele's frequency and its dominance? A) Frequency and dominance are
marshall27 [118]

Answer:

D) Frequency results from environmental stresses, not dominance.

Explanation:

The allele frequency refers to the amount of frequency of a particular allele in a small population whereas the dominance and recessive are the measure of the effects of the allele on the population which decides the trait of an organism.

The frequency and dominance cannot be correlated with each other as the frequency of the allele in a population is the result of the environmental stress which are random and by chances, whereas the effect of dominance is not random but is the result of the favoured trait for survival.

Thus, Option-D is correct.
