Which of the following gene mutations is most likely to contribute to genetic variation in a population of mammals?

A. Mutations that result from environmental factors, which affect the oldest individuals of the population.
B. Mutations that occur during DNA replication in cells that will divide to produce gametes.
C. Mutations that occur in the large intestine as a result of exposure to chemical carcinogens.



Answer :

Final answer:

Mutations in germ cells during DNA replication contribute to genetic variation in populations.


Explanation:

Mutations are the ultimate source of genetic variation in a population. In multicellular organisms, only mutations in germ cells become part of the gene pool, which occur during DNA replication to produce gametes, contributing to genetic diversity. Mutations in body cells that do not affect eggs and sperm are lost and usually do not impact evolution.
