X-linked Recessive Inheritance

X-linked recessive inheritance refers to a way that certain traits or genetic conditions are passed down through families via the X chromosome. Males have one X and one Y chromosome, while females have two X chromosomes. If a gene on the X chromosome has a mutation, males with that mutation will express the condition because they only have one X. Females, having two Xs, need both copies to have the condition; if they have one normal X, they can be carriers without showing symptoms. This is why X-linked recessive disorders are often more common in males.
