In cases of x-linked inheritance
WebGenes carried on sex chromosomes, such as the X chromosome of humans, show different inheritance patterns than genes on autosomal (non-sex) chromosomes. Jump to detailed articles and videos on these topics: Multiple alleles, incomplete dominance, and codominance (article) Pleiotropy and lethal alleles (article) Sex-linked traits (video) WebIn X-linked recessive inheritance, a female with one altered copy of the gene in each cell is called a carrier. Carrier females have about half the usual amount of coagulation factor VIII or coagulation factor IX, which is generally enough for normal blood clotting.
