14.1 Human Chromosomes
... Many human genes, including the genes for blood group, have multiple alleles. A gene located on a sex chromosome is a sex-linked gene. The genes on sex chromosomes show a sex-linked pattern of inheritance, since females have two copies of many genes (located on X chromosomes) while males have just o ...
