How much do you look like your parents? What about the other members of your family: aunts, uncles, cousins, full siblings, half-siblings? Why do some family members look nearly identical to each other, while other family members seem as if they don't share two traits? The answer to this boils down to\u00a0<em>how<\/em> traits are inherited.\r\n\r\nParents pass on traits to their children. Traits like blood type, cleft chin, dimples, and widow\u2019s peaks are all inherited in a fairly straight-forward, simple fashion. However, the inheritance of other traits is\u00a0much more complex and harder to\u00a0understand: these traits include height, skin color, and eye color.
