The kernel color of wheat is determined by three pairs of polygenes. In a cross between $AABBCC$ (dark color) and $aabbcc$ (light color),what will be the proportion of $F_2$ progeny having a kernel color similar to either of the two parents?

The phenotypic ratio obtained in quantitative inheritance of a dihybrid cross is

Inheritance of skin colour in humans is an example of

The grain color in wheat is controlled by three pairs of polygenes. When a red-grained wheat variety is crossed with a white-grained variety,an $F_1$ hybrid is produced. When the $F_1$ hybrid is self-pollinated,what fraction of the $F_2$ generation will resemble the parental phenotypes?

What are polygenes? Explain polygenic inheritance with the example of human skin color.

Explain the effect of cumulative genes on skin color.
