In genetic sex determination, if a genotype of XX is female and XY is male, what will be the natural percentage of female offspring?

Question

Quizplus · Accepted Answer

The natural percentage of female offspring in genetic sex determination is 50%. This is because each parent contributes one sex chromosome to their offspring, either an X or a Y. Since females have two X chromosomes (XX) and males have one X and one Y chromosome (XY), there is an equal chance (50%) for a child to inherit either an X or Y chromosome from their father. Thus, 50% of offspring will have two X chromosomes and be female, while the other 50% will have one X and one Y chromosome and be male.
