What are the examples of Y-linked inheritance?
Y-linked inheritance is a form of inheritance for the genes located on the Y chromosome. In humans and other mammalian males, the sex chromosomes are the X and Y chromosome. The y chromosome is smaller than the X chromosome and thus, carries relatively fewer genes.
Hypertrichosis of the ears, webbed toes, and porcupine man are examples of Y-linked inheritance in humans. Hypertrichosis of the ears (or hairy ears) is a condition wherein there is a conspicuous growth of hair on the outside rim of the ear. Webbed toes condition is characterized by having a web-like connection between second and third toes. Porcupine man is a condition when the skin thickens and gradually becomes darker, scaly, rough and bristle-like outgrowths. Since Y-linked inheritance involves the Y chromosome, Y-linked inheritance is passed on from father to son.
