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?

Fr = red fur
Fw = white fur

Cross = FrFr x FwFw

Punnett Square

        Fr        Fr
Fw| FrFw | FrFw|
Fw| FrFw | FrFw|

Since it is codominant a genotype of FrFw would result in a red and white cow. The phenotypic ration is 100% red and white cows.

The answer would be B; Their fur will be a mixture of red and white hairs.

because:

     r      r

w   rw rw

w   rw rw

meaning that all of them will have red and white fur because they are both homozygous mates, one is not superior to the other. Same would happen with capital letters.
