Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism’s resulting physical appearance shows a blending of both alleles. Incomplete dominance is a genetic phenomenon where one allele does not completely mask the effects of another when both are present in a heterozygous individual. Incomplete dominance is a fundamental concept in genetics that describes a unique pattern of inheritance
This genetic phenomenon was first identified by carl correns, a german botanist, who explored the inheritance patterns in the plant mirabilis jalapa, commonly known as four o’clock flowers. It shows that inheritance is not always about one trait completely overshadowing another. Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blending of both traits.
* neither allele completely overpowers the other * the phenotype appears as a blend of both alleles. This blending phenomenon is incomplete dominance, where genetic instructions from both parents contribute to a unique outcome in their offspring
