Incomplete dominance is a genetic phenomenon where neither of the alleles for a particular trait is completely dominant over the other, resulting in a phenotype that is a blend of the two alleles.
Snapdragon flowers provide a classic example of incomplete dominance. In snapdragons, the gene for flower color has two alleles: red (R) and white (r). When a plant carries two red alleles (RR), the flowers are red. When a plant carries two white alleles (rr), the flowers are white. However, when a plant carries one red and one white allele (Rr), the flowers are pink, displaying a blend of red and white.
This phenomenon illustrates how incomplete dominance results in an intermediate phenotype, where both alleles contribute to the final expression of the trait.
Explain incomplete dominance, using snapdragon flowers as an example.
