A.Polygenic character is controlled by multiple genes – True, because many genes control a single character.
B.Numerous intermediate types are found in between the two extremes in polygenic inheritance – True because many phenotypes are appear between the parental phenotypes.
C.Height, weight and skin colour are polygenic – True, because many genes control variety of phenotypes in the living organisms.
D.Polygenic traits is controlled by multiple alleles – False, because many genes control one trait. It is called Polygenic inheritance.
So, the correct option is ‘Polygenic trait is controlled by multiple alleles’.
