Females, however, have XX as sex chromosomes, two of them! So, do we really need two, or do females have an extra? The answer was discovered in 1961 by Mary Lyon ...

In single gene disorders, individuals in regard to the abnormal gene are one of 3 groups: a heterozygote (carrying one mutated and one normal gene and thus affected in AD and not affected in AR disorders), a homozygote for the mutated gene (and thus affected in all cases), or a homozygote normal.
