The male gamete determines the sex because it may contribute either an X or a Y chromosome.

The male gamete determines the sex because the female sex chromosomes are dormant in the zygote.

In humans, the "male gamete determines the sex of an offspring because it may contribute either an X or a Y chromosome"

Answer: Option C

Explanation:

Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.

The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).
