What is the difference between incomplete dominance and codominance answer

From the Punnett square, you can see that half of the offspring will be pure black, and the other half will have black and white spots. Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring.

An example is a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring. An example is a white flower and a red flower producing offspring with red and white patches. Interested in finding out more about genetics and molecular biology?

Incomplete Dominance vs Codominance: What's the Difference? What Is Incomplete Dominance? What Is Codominance? Codominance In codominance, both alleles are expressed together in the offspring. Examples of Incomplete Dominance and Codominance When comparing codominance vs.

Incomplete Dominance In the Punnett square below we are crossing a pure red flower RR with a pure white flower rr. These pairs of alleles may or may not be similar. That is, a heterozygous gene has two dissimilar pairs of alleles while homozygous have identical ones.

Heterozygous alleles carry different information on traits. When we say one trait is dominant over the opposite , there are often two reasons:. Incomplete Dominance and Codominance. Incomplete dominance and codominance are different from one another.

In codominance, both the alleles present on a gene are expressed in the phenotype. A flower showing codominance will have patches of red and white instead of a uniformly pink flower. In incomplete dominance, the F2 generation from heterozygous plants will have a ratio of with the phenotypes red, white and spotted flowers. The humans with AB blood type also show codominance where the alleles for both blood types A and B are expressed.

Examples of Incomplete Dominance. Examples of incomplete dominance are mentioned below:. In Humans. The child of parents each with curly hair and straight hair will always have wavy hair.

Carriers of Tay-Sachs disease exhibit incomplete dominance. In Other Animals. In its feature colors, the Andalusian chicken shows incomplete dominance When the rabbits with long and short furs are bred, the offspring produced will have medium fur length.

Incomplete Dominance. The two alleles neither act as dominant or recessive over the other. One allele is not completely dominant over the other. Both the alleles blend equally and show the traits in their offspring.

Both alleles blend, however only one of the two is noticeable in the offspring.
