You're getting terms mixed up. You are confusing incomplete dominance (also called blending or blended inheritance) with codominance.
Genetically, blood type inheritance is an example of multiple alleles & Codominance.
Answer: Type AB, co- dominance.

As you know there are 4 blood types: A, B, AB, and O. In order to get A type blood you have two allele options: AO, or AA. For B: BO or BB, for O type you need OO, since O is recessive. Therefore AB can only be made one way... with an A allele and a B one... both are dominant over O, but are they dominiant over each other?? No, they're not so, AB is a result of incomplete dominant. Another example is getting pink (RW) flowers from red (RR) and white (WW) flowers.
Now remember this and ace this genetics section! =)

In codominance, neither phenotype is dominant. Instead, the individual expresses both phenotypes. A common example is the ABO blood group system. The gene for blood types has three alleles: A, B, and i. i causes O type and is recessive to both A and B. The A and B alleles are codominant with each other. When a person has both A and B, they have type AB blood.

Blood variety refers back to the very final sugar on the tip of a glycoprotein that's located interior the plasma membranes of crimson blood cells. variety A has one sugar, variety B a distinctive in it extremely is place, and variety O lacks the terminal sugar. the situation of this sugar is coded via each and every their very own gene which we are going to call A, B, and O alleles. in the experience that your genotype is AO meaning that loci has 2 distinctive alleles at that gene. "A" on your mom's chromosome and "O" on your dad's chromosome shall we are saying. Your crimson blood cells might have some proteins with the A sugar and a few without the sugar (O). The anitbodies react to the A protein configuration (for this reason A is dominant) and the O trait won't be able to be detected that's why O is a conventional DONOR. the comparable is authentic for BO with the B protein configuration. while you're variety AB. this means your crimson blood cells might have proteins that end with the A sugar and people who end with the B sugar and no antibodies could be produced by way of fact they could attack one yet another, so AB is a conventional RECIPIENT.

The answer would be the AB bloodtype which is formed due to the incomplete dominance of the A and the B bloodtype. One would have to be from each parent.
Hope this helps.

Incomplete dominance is the opposite of complete dominance. Complete dominance is when there the red flower completely over rides the white flower. Incomplete dominance is when the red flower and white flower combine to make a pink flower.
I thought I would define incomplete dominance since everyone else gave you your answer. Good Luck!
