Question

In addition to autosomes, what is contained in a human sperm cell?
A) an X chromosome always
B) either an X or a Y chromosome
C) a Y chromosome always
D) both an X and a Y chromosome

Human sperm cells contain either an X or a Y chromosome. This is because the father's sperm determines the sex of the child by contributing either an X or Y chromosome during fertilization. Therefore, half of the sperm cells will contain an X chromosome and the other half a Y chromosome.
