Answer 1

The chromosomal constitution of a human female can be written as 44 + XX.

Explanation:

Man has a total of 46 chromosomes, divided into 23 pairs. There are 44 autosomes and two sex chromosomes among the 46 chromosomes. Because men are heterogametic, their chromosomal constitution is 44 + XY, whereas women are homogametic, so their chromosomal constitution is 44 + XX.
