The difference between dominant and recessive inheritance patterns also plays a role in determining the chances of a child inheriting an X-linked disorder from their parentage. [citation needed] X-linked dominant disorders tend to affect females more often because they tend to be developmentally fatal in males.

Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
The disorder is inherited in an X-linked dominant manner. [ 1 ] [ 2 ] This means the defective gene responsible for the disorder (PHEX) is located on the X chromosome, and only one copy of the defective gene is sufficient to cause the disorder when inherited from a parent who has the disorder.
Autosomal recessive inheritance, a 25% chance, and (purple) a 50% carrier chance. Autosomal recessive traits is one pattern of inheritance for a trait, disease, or disorder to be passed on through families. For a recessive trait or disease to be displayed two copies of the trait or disorder needs to be presented.
An example pedigree chart of an autosomal dominant disorder An example pedigree chart of an autosomal recessive disorder An example pedigree chart of a sex-linked disorder (The gene is on the X chromosome.) The description of a mode of biological inheritance consists of three main categories: 1. Number of involved loci
The difference between dominant and recessive inheritance patterns also plays a role in determining the chances of a child inheriting an X-linked disorder from their parentage. In LFS, X-linked dominant inheritance was suspected, as boy and girl siblings in one family both exhibited the disorder.
The difference between dominant and recessive inheritance patterns also plays a role in determining the chances of a child inheriting an X-linked disorder from their parentage. [citation needed] A locus of Xq24-q27 has been described. [3]
