Can someone explain the answer?
Codominance is a form of inheritance in which two different alleles for a gene are both expressed, and neither allele is dominant over the other. One example of codominance is fur color in cattle; the alleles for red fur and white fur are codominant. If a homozygous red cow and a homozygous white bull mate, what would you expect to find in their offspring?

They will all have white fur.

Their fur will be a mixture of red and white hairs.

Their fur will be pink.

They will all have red fur.

Codominance is kind of like "blending", when you have one of each of the alleles you get a phenotype that is between the two. 

What colour do you get when you mix white and red paint?

Pink.

Well knock me down their fur is pink...that's interesting.

aaronq · Answer

oh wait, I'm thinking of incomplete dominance. (they're very similar)

in incomplete dominance you would get "blending", so you would see pink.

in codominance you would get red and white spots.

sorry for the confusion
