Question

the sex of a child is determined by the __________. a sperm b egg c either sperm or egg

Explanation:

In humans, females have two X chromosomes (XX) and produce eggs with an X chromosome. Males have one X and one Y chromosome (XY) and produce sperm with either an X or a Y chromosome. When a sperm with an X chromosome fertilizes an egg (X), the child is female (XX). When a sperm with a Y chromosome fertilizes an egg (X), the child is male (XY). So the sex - determining factor is the sperm as it can carry either X or Y, while the egg only carries X.

Answer:

A. sperm
