Answer:

C. This mutation occurs in all male but no female offspring of a male with the mutation.

Step-by-step explanation:

A. This mutation occurs in all offspring of a male with the mutation. THIS IS FALSE, SINCE THE MALE CAN HAVE FEMALE OFFSPRING, AND THOSE INDIVIDUALS WILL HAVE XX SEXUAL CHROMOSOMES, THEY WILL NOT INHERIT A Y CHROMOSOME.

B. This mutation occurs in all male but no female offspring of a female with the mutation. THIS IS FALSE, SINCE A FEMALE INHERITS X CHROMOSOMES.

D. This mutation occurs in all offspring of a female with the mutation. THIS IS FALSE, SINCE A FEMALE INHERITS X CHROMOSOMES.
