Sex chromosomes are the chromosomes which determine whether an individual organism is male or female.


In mammals, there is one pair of sex chromosomes, which, in humans, are called X and Y. Individuals possessing XX are female, whilst those which possess XY are male.


The Y chromosome contains a gene called SRY, which determines whether or not the embryo will develop testes, which are responsible for the development of male sexual characteristics. So, it is the absence of a male chromosome that causes femaleness.


The sex chromosomes also carry genetic information which codes for characteristics other than those concerned with gender. These are called sex-linked characteristics.
