The formation of a third phenotype specifically with traits that results from the combination of parent alleles is known as incomplete dominance or. The intermediate trait appearance in between the phenotypes of homozygous traits in the heterozygote is called incomplete dominance.For example, the pink color of flowers (such as snapdragons or four o’clock flowers), the shape of hairs, hand sizes, voice pitch in humans. The incomplete dominance is referred to as the dilution of the dominant allele with respect to the recessive allele, resulting in a new heterozygous phenotype.Incomplete dominance is defined differently as follows: Punnett square shows all the possible traits (genotypes) of the new offspring in graphical or table form after the crossing of homozygotes. The genotypic ratio is better understood through the Punnett square.
