Mutations and polymorphisms are both changes in a dna sequence, but polymorphisms are more common becausea. they less severely affect the phenotype, so that individuals can reproduce and transmit them. b. more people have them. c. mutations are always lethal. d. they more severely affect the phenotype, so that individuals cannot reproduce and transmit them. e. mutations refer to a real situation, whereas a polymorphism is an idealized state that biologists hypothesized to explain genetic change.

Option A. they less severely affect the phenotype, so that individuals can reproduce and transmit them

Explanation:

Polymorphism is the genetic variation found within a population, which favors the process of natural selection. It prefer successful traits in population.

While, mutation is the alteration of DNA sequence of an organism. Mutation can cause loss of traits in the population.
