What gender is an XXY chromosome?

There are 2 types of chromosome, called the sex chromosomes, that determine the genetic sex of a baby. These are named either X or Y.

Why do we have two sexes?

and allowing only half of the organisms genes to end up in each of its offspring). When sex does evolve, two sexes are favoured because that is the easiest way to prevent competition between the organelles of the parents. An organism’s organelles are all aquired from its mother.
