Detailed explanation-1: -Height is a polygenic trait which is controlled by at least three genes with six alleles. Polygenic inheritance shows continuous variation. There is no distinct alternative like tall and short, rather there is a whole range of possible heights.
Detailed explanation-2: -Human height is an example of inheritance while human blood group is an example of inheritance.
Detailed explanation-3: -Three examples of polygenic traits in humans are height, skin colour and eye colour. These traits are governed by multiple genes.
Detailed explanation-4: -Examples of human polygenic inheritance are height, skin color, eye color and weigh.
Detailed explanation-5: -A complex inheritance pattern. How, then, is height inherited? Height and other similar features are controlled not just by one gene, but rather, by multiple (often many) genes that each make a small contribution to the overall outcome. This inheritance pattern is sometimes called polygenic inheritance (poly-= many).
