1. If a red flower (RR) and a white flower (rr) were crossbred, resulting in 100% Rr, what phenotypes would be seen according to
Digiron [165]

Answer: 1) The phenotype of Rr is Pink according to incomplete dominance.

Incomple dominance occurs when none of the alleles is completely dominant over the other, resulting in blending of the phenotype from the parents. When a red (RR) and a white flower (rr) are crossbred, they result in Rr that is a pink phenotype.


2) According to Codominance, the phenotype of Rr is Red and White flower.

Codominance occurs when both the alleles are equally expressed. In this case allele for Red (R) and white (r) phenotype are expressed equally giving Red and White flower.


3) In Codominance, both the alleles are visible in the hybrid and in Incomplete dominance, intermediate (blend of parental) phenotype is visible in the hybrid.
