Male sex chromosomes. Computer artwork of an X and Y symbolising the male sex chromosomes. An individual's sex is determined by the presence or absence of the Y chromosome. Women have two X chromosomes,while men have an X and a Y. Chromosomes consist of very condensed deoxyribonucleic acid (DNA). DNA contains sections,called genes,which encode the body's genetic information. The Y chromosome only contains genes for 'maleness',for example a gene that triggers the development of the testes,and is much smaller than the X chromosome | |
