Question

Quizplus · Accepted Answer

In males, the X and Y chromosomes determine sex and are different from the other 22 pairs of autosomes. The Y chromosome is smaller and contains fewer genes than the X chromosome. Genes on the X and Y chromosome do not have a second copy, as males only inherit one X chromosome (from their mother) and one Y chromosome (from their father). This is different from autosomes, where each gene has a pair of copies (one from each parent).
