Each of your cells contains two copies of 23 chromosomes, one inherited from your father and one from your mother. Theoretically, when you create a gamete—a sperm or an egg—each copy has a 50-50 shot at being passed on. ...

Cell division is the basis of life and requires that each daughter cell receive the proper complement of chromosomes. In most organisms, this process is mediated at the familiar constricted intersection of X-shaped chromosomes. ...
