In tomatoes,a plant with the genotype $aabbcc$ produces $100 \,g$ tomatoes,and a plant with the genotype $AABBCC$ produces $160 \,g$ tomatoes. What is the contribution of each polygene to the tomato weight (in $,g$)?

Human skin colour is an example of:
$I.$ Multiple gene inheritance
$II.$ Three separate genes controlling this trait
$III.$ Single gene controlling this trait
$IV.$ Two genes controlling this trait
$V.$ Environment plays a significant role in this trait
Choose the correct option.

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?

Define/Explain: Polygenic Inheritance.

An example of a quantitative trait in humans is .....

The phenotype of one parent for skin colour is $AABBCC$ and the other parent is $aabbcc$. What will be the skin colour and genotype for their progeny?
