Solution
The correct option is A XY
In humans, sex is determined by sex chromosomes (XX females, XY males).
A female child (44A + XX) is the result of the fertilization of an egg (22 + X) with sperm carrying 22+X chromosomes.
A male child (44A + XY) is the result of the fertilization of an egg (22 + X) with sperm carrying 22+Y chromosomes.
Thus, the offspring can be of two types, XX and XY.
