Incomplete dominance occur when two allele expresses itself in the phenotype of an organism.

Its a situation where by an allele is not dominant over another other in an heterozygous condition but it gives a blend of the two allele in the phenotype of the offspring.

Example is the phenotype of a 4'o clock plant that gives pink flower when a red flower is crossed with white flower.
