Answer:
In codominance, two dominant genes express itself in appearance (phenotype). For example, In people with AB blood types, A and B are both dominant genes and both try to show themselves in blood type, which forms third blood type AB.
In incomplete dominance, the organisms with heterozygous genotype (Aa) will have a blended trait instead of showing dominant trait because dominant gene (A) cannot show itself necessarily in appearance (phenotype). For example, when a plant with homozygous red flower (dominant and AA) is crossed with white flower (recessive- aa), the resulting offspring will all have heterozygous flowers (Aa) and pink (blended), instead of showing dominant trait (red).
