... both phenotypes because A and B express a special dominance relationship: codominance . Thus, it is usually impossible for a type AB parent to have a type O child (it is, however, no direct proof of illegitimacy ). Evolutionary biologists theorize that the A allele evolved earliest, followed by O and t...

...es in the phenotype. One exception is incomplete dominance (sometimes called blending inheritance ) when alleles blend their traits in the phenotype . An example of this would be seen if, when crossing flowers with codominant "blue" and "purple" alleles for petal color, the resulting offspring would have...
