Detailed explanation-1: -The crossing of a red flowered plant and a white flowered plant produces all the offspring with pink flowers. This cross illustrates red and white exhibit incomplete dominance. This situation occurs due to the blending of both the alleles.

Detailed explanation-2: -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-3: -This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time. The allele for red flowers is incompletely dominant over the allele for white flowers. Red + white = pink.

Detailed explanation-4: -Pink roses are often the result of incomplete dominance. When red roses, which contain the dominant red allele, are mated with white roses, which is recessive, the offspring will be heterozygotes and will express a pink phenotype.

Detailed explanation-5: -The Carnation plant (which is an example of incomplete dominance) has true-breeding white flowers and true-breeding red flowers. A cross between white-and red-flowering carnation plants may result in offspring with a phenotype of pink flowers. Four o’clock flowering plants are an example of incomplete dominance.
