Detailed explanation-1: -Answer and Explanation: A cross between a red rose and a blue rose will most like result in a purple rose if the trait is determined by incomplete dominance.

Detailed explanation-2: -2. A rose shows incomplete dominance; when a red-flowered plant is bred with a white-flowered plant, the offspring are pink with the phenotype Rr.

Detailed explanation-3: -Incomplete dominance is a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype. It is also known as partial dominance. For eg., in roses, the allele for red colour is dominant over the allele for white colour.

Detailed explanation-4: -The allele for red flowers is incompletely dominant over the allele for white flowers. Red + white = pink. The results of a cross where the alleles are incompletely dominant can still be predicted, just as with complete dominant and recessive crosses.

Detailed explanation-5: -The plants that show incomplete dominance with respect to color of its flower are Mirabills jalapa and Antirrhinum sps. Was this answer helpful?
