[QUOTE="randiliana, post: 647526, member: 2308"] [i]However, there are exceptions to the way heterozygotes express themselves 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 Antirrhinums—flowers with incompletely dominant "red" and "white" alleles for petal color—the resulting offspring had pink petals. Another exception is co-dominance, where both alleles are active and both traits are expressed at the same time; for example, both red and white petals in the same bloom or red and white flowers on the same plant. Codominance is also apparent in human blood types. A person with one "A" blood type allele and one "B" blood type allele would have a blood type of "AB".[/i] [i]Co-dominant/Incomplete Dominant: The heterozygous genotype is a visible mutant phenotype but the homozygous genotype is a different visible mutant phenotype.[/i] I finally had time to look this up, I had just taken for granted that what the articles said was true. Most of what I found treats co-dominace and incomplete dominance as different terms for the same trait. They seem to be pretty interchangable, but in the few instances where they defined them separately, you guys seem to be correct. [/QUOTE]
