Question
What is the key to the recognition of incomplete dominance?The trait exhibits a continuous distribution.The alleles affect more than one trait.The phenotype of the heterozygote falls between the phenotypes of the homozygotes.The heterozygote expresses the phenotype of both homozygotes.
Solution
The key to the recognition of incomplete dominance is that the phenotype of the heterozygote falls between the phenotypes of the homozygotes. This means that the heterozygote, which has two different alleles, shows a phenotype that is intermediate between the two homozygotes, which each have two identical alleles. For example, if a red flower and a white flower cross-pollinate, the resulting offspring might be pink, which is an intermediate phenotype. This is different from complete dominance, where the heterozygote expresses the phenotype of one of the homozygotes.
