What is incomplete dominance? Explain it with the help of a cross.

Explanation

Incomplete Dominance (Intermediate Inheritance). Incomplete (partial) dominance is the phenomenon where none of the two contrasting alleles or factors is dominant. The expression of the character in a hybrid or F individual is intermediate or a fine mixture of the expressioni if the two factors (aš found in homozygous state). Carl corners reported incomplete dominance in case of flowers of Mirabilis o.clock plant) and Antirrhinum majus (Snap dragon or Dog flower). In both plants have two typ sof flower colours in puré state-red and white. When the two types of plants are crossed, the hybı dor plants of F, generation have pink flowers. If the latter are selfed, the plants of F, generation ac or three types-red, pink and white flowered in the ratio of 1:2:1. The pink colour apparently appetin either due to mixing of red and white colours (incomplete dominance) or expression of a single g. 19 for pigmented flower which produces only pink colour (quantitative inheritance).
