Solution

The correct option is A 22
Humans have 23 pairs of chromosomes in each cell. Among them, 22 pairs are autosomes and 1 pair is of sex chromosomes.
In females, both the sex chromosomes are X chromosomes. Whereas, sex chromosomes in males are X and Y.
Zygotic cell formed after fertilization of sperm and ovum contain 46 chromosomes with 23 chromosomes from each parent. Sperm has either 22+X or 22+Y and ovum has 22+X. Hence, there are 22 autosomes in a human gamete.
