In other words, the trait is not completely dominant - or, it is neither dominant nor recessive. Moreover, some definitions show incomplete dominance where the new offspring has a specific trait with less intensity than the dominant trait among the paired alleles. Whereas, several definitions define incomplete dominance as a phenomenon in which the heterozygote possesses an intermediate trait between the two homozygous traits. ![]() The incomplete dominance is referred to as intermediate inheritance in terms of trait expression, and none of the alleles from the paired alleles expressed over the other for a particular trait.Īccording to some definitions, there are several assumptions about incomplete dominance incomplete dominance occurs due to the combination of parent alleles, both dominant and recessive.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, and 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 or genotype ratio is better understood through the Punnett square. The number of times of trait appearance in the offspring after crossing the genes or alleles of the specific trait identified through the genotypic ratio.Phenotype is determined by the genotype and refers to the organism’s appearance, characteristics, behavior, and development (physically observable features). A set of genes in an organism that is inherited by the offspring and that determines the offspring’s observable physical features is called the genotype. ![]() An organism that possesses two different alleles for a specific gene is described as heterozygous.
