because they have an X and a Y chromosome while females have two X chromosomes. chromosomes hold genes which are comprised of dna. these genes are like the building instructions that tell the cells in your body what to do. the Y chromosome is much shorter than the X chromosome, so there are less genes in a man than a woman. some say it makes us lesser beings, others say it makes us simpler. But heres the thing, the most simple and therefore the most adaptable organisms are the organisms that always survive.
