Question

The human male gamete with X chromosome fuses with a female gamete to form a zygote. The offspring will be a male child.

• A. True
• B. False

Answer 1

The correct option is B

False

Human males have XY as their sex chromosomes, so the male gamete can have either X or Y chromosome. And the human females have the XX as the sex chromosomes, hence the female gamete or egg always has the X chromosome.
In this case, the male gamete with the dominant X chromosome will fuse with the female egg that also has another X chromosome. So the offspring will have an XX chromosome pair which means the offspring will be a female child.
Sex determination in humans is based on XX-XY system, therefore, XX means female XY means male.
