Question

After mitotic cell division, a female human cell will have:

• A. 44 + xx chromosome
• B. 44 + xy chromosome
• C. 22 + x chromosome
• D. 22 + y chromosome

Answer 1

The correct option is A

44 + xx chromosome

The correct option is A.

Explanation of the correct option :

1. Human females have 46 chromosomes organized into 23 homologous, homomorphic pairs.
2. There are 22 autosome pairs and one sex chromosome pair (44 + XX).
3. Mitosis is an equatorial division that results in daughter cells that have the same number of chromosomes as the parent cell.
4. Mitosis in a human female cell would therefore result in progeny cells with 44 + XX chromosomes.

Final answer: After mitotic cell division, a female human cell will have 44 + xx chromosome.
