Question

2. If red (R) and white (r) are codominant

alleles that determine flower color, what
phenotypes are possible for this gene?
A. Red and white
B. Pink only
C. Red, white, and pink
D. Red, white, and red-white
spotted​

Answer 1

D. Red, white, and red-white spotted

Step-by-step explanation:

Co-dominance is when neither allele is dominant, and both are expressed. That means you would see patches of both red and white if the individuals were heterozygous, so D is correct.

In incomplete dominance, one allele is not entirely dominant over the other. giving an intermediate or blended phenotype between the two traits, this would result in a pink phenotype if the individuals were heterozygous.
