D) Mutation rate increases with genome size in unicellular organisms.

Question

Quizplus · Accepted Answer

Mutation rate per base pair tends to decrease with increasing genome size in multicellular organisms, likely due to more effective DNA repair mechanisms and the lower tolerance for mutations in larger genomes, which could have more deleterious effects.
