Explanation:
Polygenic inheritance is a phenomenon shown by a trait that is controlled by many genes residing at different loci.
Thus, the expression of the trait is the total effect of all the genes controlling it. Skin colour and height in humans are examples of such traits.

Answer:
A. 3/16
Explanation:
The four possible outcomes for Stem length are:
Tt, tT, TT and tt.
The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.
The four possible outcomes for flower coloration are:
Rr, rR, RR and rr.
The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.
Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

Therefore, the answer is A. 3/16
