X-Linked Recessive
X-Linked Recessive is a type of genetic inheritance where a gene responsible for a trait or disorder is located on the X chromosome. Males, having one X and one Y chromosome, are more likely to express X-linked recessive conditions because they have only one copy of the X chromosome. If that X chromosome carries a mutation, the male will show the trait or disorder.
Females have two X chromosomes, so they can be carriers of the mutation without showing symptoms. If a female inherits one affected X chromosome, she may pass it on to her sons, who would then express the condition. Examples of X-linked recessive disorders include hemophilia and Duchenne muscular dystrophy.
