X-linked recessive
X-linked recessive is a type of genetic inheritance where a gene located on the X chromosome is mutated. This condition primarily affects males, as they have only one X chromosome and one Y chromosome. If a male inherits the mutated gene, he will express the trait or disorder. Females, having two X chromosomes, can be carriers if they have one mutated gene but typically do not show symptoms unless both X chromosomes carry the mutation.
Conditions like hemophilia and color blindness are examples of X-linked recessive disorders. In females, the chance of expressing the disorder increases if they inherit the mutated gene from both parents. Genetic counseling can help families understand the risks and implications of X-linked recessive inheritance.
