Question

Assume that a particular human cell is examined under a microscope, and it contains 22 autosomes and a Y chromosome. This cell is most likely to be _____

Answer 1

A sperm cell

Step-by-step explanation:

A diploid cell has 46 chromosomes which is normally signified by somatic cells. Germ cells or gametes are haploid cells therefore they contain only 23 chromosomes. Male gamete contains 22 autosomes and one sex chromosome. That sex chromosome can be X or Y.

Female gamete does not have Y chromosome as a sex chromosome, it has only X chromosome as a sex chromosome. So Y chromosome in a human cell which have 22 autosomes determines that it is a male gametic cell or a sperm cell. Sperm cells that have a Y chromosome if fuses with female gamete produce male offspring(XY).

So the correct answer is- a sperm cell.
