Answer:
B. somatic mutations may be passed to daughter cells by mitosis.
Step-by-step explanation:
In multicellular organisms, somatic mutations may be passed to daughter cells by mitosis.
Mitosis has to do with the division of somatic cells as opposed to germ or reproductive cells. Hence, daughter cells from mitosis are exact copies of their parents. If a mutation occur in the somatic cell of a parent, such could be passed to the daughter cell through mitosis.
Somatic mutations cannot be passed via sexual reproduction. Sexual reproduction can only be used to passed germline mutations.
Not all mutations produced phenotypic changes. Some mutations are silent and have no phenotypic implications.
Not all mutations are point mutations.
The correct option is B.
