Parent plants?

Question

This entire thing confuses me, please explain.

I know that in some plant species, pink flowers result from incomplete dominance. What traits would be present in the parent plants used in this cross?

be detailed.

Answer 1

The pink flowers are a result of incomplete dominance of the genes for red and white flowers. This is a well-known example of incomplete dominance, and it occurs in carnations. R is the gene for red pigment, and R' is the gene for no pigment. A flower with genotype RR produces a lot of red pigment, and appears deep red; that is to say, its phenotype is red. A R'R' genotype results in no pigment at all, and a white phenotype. A RR' genotype, the heterozygous situation, results in only a small amount of red pigment being produced, and thus a pink phenotype.
