Solution

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.
