The authors suggest that this could happen in up to 1 in 20, genetically male embryos XY. The inheritance pattern describing a dominant trait or condition caused by a mutation in a gene on the X chromosome. Sex-linked diseases are passed down through families through one of the X or Y chromosomes. An abnormal gene on the X chromosome from each parent would be required, since a female has two X chromosomes. If a man has an X-linked recessive disorder and his mate does not carry the allele for it, all of their girls will be carriers. In this pedigree, the carrier heterozygous females are indicated; however, they do not express the trait being tracked in this pedigree.

Sex cell inheritance patterns for male and female children. This explains why women are frequently carriers of X-linked traits but more rarely have them expressed in their own phenotypes. If you're seeing this message, it means we're having trouble loading external resources on our website. Most of them code for something other than female anatomical traits. Affected males are hemizygous for the X-linked trait. Females can get an X-linked recessive disorder, but this is very rare. Examples of X-linked recessive traits are hemophilia A, hemophilia B, Duchenne muscular dystrophy, and glucosephosphate dehydrogenase deficiency.

Examples of X-linked recessive traits are hemophilia A, hemophilia B, Duchenne muscular dystrophy, and glucosephosphate dehydrogenase deficiency. Textbook of Family Medicine. All of them were men, as expected. Most X-linked traits in humans are recessive. In this pedigree, the carrier heterozygous females are indicated; however, they do not express the trait being tracked in this pedigree.
