PATHOLOGY

Detailed explanation-1: -Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. 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.

Detailed explanation-2: -Incomplete Dominance and Codominance A flower showing codominance will have patches of red and white instead of a uniformly pink flower. In incomplete dominance, the F2 generation from heterozygous plants will have a ratio of 1:2:1 with the phenotypes red, white and spotted flowers.

Detailed explanation-3: -The inheritance of color in snapdragon is an example of Incomplete Dominance. It is a form of intermediate inheritance in which one allele for a particular trait is not expressed completely over its paired allele.

Detailed explanation-4: -In snapdragons, flower color is controlled by incomplete dominance. The allele for red is R and the allele for white is W.
