X-Linked Inheritance

X-linked inheritance refers to traits or disorders caused by genes located on the X chromosome, one of the two sex chromosomes. Since males have one X and one Y chromosome, a single faulty gene on their X chromosome can result in the trait or condition being expressed. Females have two X chromosomes, so a healthy copy can often compensate for a defective one, making them less likely to show symptoms. This pattern explains why certain conditions, like hemophilia or color blindness, are more common in males, while females are usually carriers without showing signs.
