How does incomplete dominance differ from co-dominance?

Incomplete dominance is a type of genetic interaction where the phenotype of an organism is determined by the blending of the expression of two traits. The phenotype is intermediate between the two different expressions. For example, when a red-flowering plant is crossed with a white-flowering plant, the resulting progeny might produce pink flowers. Co-dominance occurs when each allele for a gene is expressed equally in the phenotype of the organism. For example, when a black-haired parent and a blonde-haired parent have a baby, the baby might have black and blonde streaks in their hair. Both alleles at the given genetic locus are equally expressed, so the resulting phenotype is not intermediate between either the black or the blonde parent.
