What is True breeding plant?

A true breeding is a kind of breeding wherein the parents would produce offspring that would carry the same phenotype. This means that the parents are homozygous for every trait.

An example of true breeding is that of the Aberdeen Angus cattle. The cattle have been black for many generations, which is an indication that such trait passed on from many generations remains pure.

With plants, true breeding occurs when plants produce only offspring of the same variety when they self-pollinate. For instance, a plant that has blue flowers will produce only seeds that will grow into plants that have blue flowers.

Therefore, A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F, offspring are yellow.  The question can be Is flower color polygenic?
