Question

The difference between incomplete dominance and codominance is:

a. that in incomplete dominance, the trait under observation is produced by the combination of multiple alleles, while in codominance, the trait is produced by a single allele.
b. that in incomplete dominance, the offspring exhibit the traits of both parents, while in codominance, the offspring do not exhibit the traits of either parent.
c. that in incomplete dominance, the trait under observation is produced by a single allele, while in codominance, the trait is produced by a combination of multiple alleles.
d. that in incomplete dominance, the offspring do not exhibit the traits of either parent, while in codominance, the offspring exhibit the traits of both parents.
e. there is no difference, incomplete dominance and codominance mean the same thing.

Answer 1

The answer is D.
In incomplete dominance, the offspring has a blending of parent traits.
Example: tall and short make medium or red and white make pink.
Thus, the offspring does not have either parent's traits.
In codominance, the offspring has a combination of traits.
Example: A white chicken and a black chicken make a speckled white and black chicken.
