All males are hemizygous while all females are heterozygous.

There's no homozygous females (because of the random inactivation of one of the X chromosomes).

The inheritance follows one of two patterns:

  1. Both males and females are affected and the typical example is X linked hypophosphotemic rickets.
  2. Manifested only in females and is lethal in utero in males. Examples include incontinenta pigmenti, focal dermal hypoplasia, and orofaciodigital syndrome.
