Question

A human cell containing 22 autosomes and a Y chromosome is probably a

• A. Somatic cell of a male
• B. Sperm cell
• C. Somatic cell of a female
• D. Unfertilized egg cell

Answer 1

The correct option is B Sperm cell

In humans, each cell nucleus contains 23 pairs of chromosomes, a total of 46 chromosomes. The first 22 pairs are called autosomes. The chromosomes of the 23rd pair are called autosomes consisting of two X chromosomes in most females, and an X chromosome and a Y chromosome in most males. The X chromosome is always present as the 23rd chromosome in the ovum, while either an X or a Y chromosome can be present in an individual sperm.

So the correct option is 'sperm cell'.
