As opposed to this, ‘incomplete dominance’ is when the phenotype of the heterozygote is not completely identical, but instead, is an intermediate of the phenotypes of homozygotes. Such a situation, wherein no single trait is dominant, or recessive, is referred to as ‘incomplete dominance’ in genetics.Īs suggested by Mendel’s principle of dominance, the situation wherein the phenotype of a heterozygote is completely identical to the phenotypes of the dominant homozygotes is referred to as ‘complete dominance’.
Instead, the offspring demonstrates intermediate traits with some inclination towards the trait of either parent. Eventually, however, it was discovered that there do exist cases wherein neither trait is dominant. Gregor Mendel, a renowned Augustinian monk and botanist, was the first person to show that crossbreeding of two species results in a hybrid offspring, which shows the traits of both parents one of which is quite prominent (dominant), while other is hidden (recessive). However, there are times when some people find it a bit difficult to grasp the same, and this is where its examples come into the picture.
A form of inheritance, incomplete dominance is one of the most interesting concepts in genetics.
