If a sperm carrying a Y chromosome fuses with the egg, what will be the sex of the child?

Answer and explanation

Correct answer: Male child

The egg always contributes an X chromosome, whereas a sperm may contribute either X or Y. When a Y-bearing sperm fuses with the X-bearing egg, the zygote has the chromosome combination XY. In the usual human sex-determination system, XY develops as a male child. Therefore, option B is correct. Option A would result from XX; options C and D do not describe this fertilisation outcome.
