X-linked disorders result from mutated genes on the X chromosome. Males, who have only one X chromosome (i.e., they are hemizygous ), will fully express an X-linked disorder. On the other hand, females, who have two X chromosomes, will be carriers of the defect in the majority of cases, and so they are usually asymptomatic.

WebAs is illustrated in the two pedigrees of Fig. 5, the hallmark of XL inheritance is the absence of male-to-male transmission. A heterozygous female has a 50% chance of transmitting the mutation to a son or a daughter, whereas a hemizygous male transmits the mutation to all his daughters but not to his sons. Fig. 5.

WebIn X-linked dominant inheritance, the gene responsible for the disease is located on the X-chromosome, and the allele that causes the disease is dominant to the normal allele in females.
