Step 1: Incomplete dominance is a genetic phenomenon in which the phenotype of heterozygous individuals is intermediate between the two homozygous phenotypes.
Step 2: In this case, neither allele is completely dominant over the other. An example is the inheritance of flower color in snapdragons, where red-flowered plants (RR) are crossed with white-flowered plants (WW). The offspring (RW) have pink flowers, showing an intermediate phenotype.
