Which genetic mutation can be passed to the offspring?

A

A gamete containing an extra chromosome is formed.

B

Excessive sun exposure causes uncontrolled mitosis in skin cells.

C

The DNA of a lung cell is damaged by exposure to cigarette smoke.

D

A cell of a reproductive organ contains a damaged chromosome.

A gamete containing an extra chromosome is formed.

Explanation:

Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.
