Question #16c23

1 Answer

Those are sex chromosomes - determining gender.


the chromosome is X or Y and when you combine them(both the father and the mother) you get or XX or XY.
The gender is usually determined by looking at the 23rd chromosome pair; when it is XX it means that it is a female and when it's XY, it means that it is a man.
