Question

in humans, what determines the sex of offspring, and why?
the male gamete determines sex because each male gamete can contribute either an x or a y
chromosome.
the female gamete determines sex because only the female gametes can have one of two functional
sex chromosomes.
the male determines sex because the sperm can fertilize either a female egg or a male egg.
the female gamete determines sex because only the female gamete provides cytoplasm to the zygote.
the chromosome contribution from both parents determines sex because the offspring uses all the
parents chromosomes.

Explanation:

In humans, sex is determined by the combination of sex chromosomes. Females have two X chromosomes (XX), and their gametes (eggs) always carry an X chromosome. Males have one X and one Y chromosome (XY). Their gametes (sperm) can carry either an X or a Y chromosome. When fertilization occurs, if a sperm with an X chromosome fertilizes the egg (which has an X), the offspring will be female (XX). If a sperm with a Y chromosome fertilizes the egg, the offspring will be male (XY). So, the male gamete determines the sex because each male gamete can contribute either an X or a Y chromosome.

Answer:

The male gamete determines sex because each male gamete can contribute either an X or a Y chromosome.
