Gonosomal recessive inheritance

Gonosomal recessive inheritance is the transmission of the observed trait, the allele oh which lies gonosome, namely chromosome X (X-linked inheritance). Few genes are located on the chromosome Y, eg. SRY. The increased pubic hair previously reported as an example of a Y-linked trait (OMIM: 425500), is probably not strongly linked to the Y chromosome.

A typical manifestation is a far greater number of sick men than women, who are overwhelmingly only healthy carriers.

Deviations
Some inconsistencies may arise because carriers have different degrees of disease manifestation. It is caused by random lyonization of one of the X chromosomes in each cell of the body. This can occur, for example, in hemophilia.

Examples

 * Hemophilia A (OMIM: 306700)
 * Hemophilia B (OMIM: 306900)
 * Color blindness (OMIM: 303800)
 * Duchenne muscular dystrophy (OMIM: 310200)
 * Becker muscular dystrophy (OMIM: 300376)
