Codominance Review (Need Scratch Paper)

A condition in which both alleles for a gene are expressed so that both traits are visible is known as ---

• Codominance

• Incomplete dominance

If a red bug and a white bug mate, their babies have red and white spots. This is most likely due to what pattern of inheritance?

• incomplete dominance

• codominance

• polygenic inheritance

Codominance sometimes uses superscripts for alleles. Which is an example of codominant alleles?

A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?

• Incomplete Dominance

In chickens, feather color is codominant. If a black chicken (C^BC^B) is mated with one that is black and white (C^BC^W) what are the chances of having a chicken that is black and white?

• 50%

In some carnations, flower color exhibits codominance. Identify the correct genotypes for red, white, and speckled carnations.

• Red = C^RC^R, white = C^WC^W, speckled = C^RC^W

• Red = C^RC^R,white = WW, speckled = rw

• Red = RR, white = C^wC^W, Speckled = C^RC^W

• Red = RR, white = WW, speckled = RW
