Incomplete dominance

Explanation:

In incomplete dominant, a new character has arisen. In this phenomenon, neither the dominant character nor the recessive character is expressed in heterozygous condition. Incomplete dominance is also called as semi-dominance or partial dominance. In this case, the blending of both dominant and recessive traits takes place. It is an example of Mendelian deviation as it does not obey Mendelian rule. For example, a cross between a red flower and a white flower gives rise to a pink flower.
