  3. Further Discussion • A disease male will always produce an affected or disease female offspring. • A disease male can only produce a disease male offspring if mated with a disease or carrier female. • Because a female has two X chromosomes, the disease generally needs to be present on both for a disease female to occur. However, mutation that suppresses the “normal” X chromosome would cause a disease female. • When the disease is not common and genetic diversity is adequate, disease females become rare.
