Twenty-two pairs of chromosomes are referred to as autosomes, since they do not determine the sex of an individual. The twenty-third pair are the sex chromosomes, generally referred to as the X and Y chromosomes. Each chromosome contains thousands of individual genes. These genes determine an individual's characteristics.
