Which Statement Accurately Describes a Relationship Between Mutation Rate and Genome

Question

Which statement accurately describes a relationship between mutation rate and genome size?
A) Larger genomes have higher mutation rates across all domains of life.
B) Larger genomes have lower mutation rates across all domains of life.
C) Mutation rate increases with genome size in multicellular organisms.
D) Mutation rate increases with genome size in unicellular organisms.

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.
