In classical genetics, incomplete dominance refers to the situation where an organism demonstrates a blended or combined phenotype due to inheriting a heterozygous genotype (the situation when one of the alleles is dominant and the other recessive). In the case of incomplete dominance, the traits defined by the alleles are blended together to create an intermediate phenotype. Neither allele has dominant control over the trait. A cross of two intermediate phenotypes can result in the reappearance of either the parent phenotypes or the blended phenotypes. Wikipedia does not have an article with this exact name. ...

An example of incomplete dominance in humans is mordan, a trait that is exhibited when eye color alleles from the maternal and paternal chromosomes are blended. This usually occurs when one parent has green eyes and the other parent has brown eyes–the child will have dark blue eyes.
