Question

Let R = red pigment and r = no pigment. In carnations, RR offspring make a lot of red pigment, rr offspring make no pigment, and Rr offspring make a small amount of red pigment, thus appearing pink. Pink carnations are therefore an example of?

Answer 1

Pink carnations are an example of incomplete dominance, also known as codominance, in genetics. The combination of the red allele (R) and the absence of pigment allele (r) in the heterozygous offspring (Rr) produces a small amount of red pigment, giving the flowers a pink appearance.

Step-by-step explanation:

Pink carnations are an example of incomplete dominance, also known as codominance, in genetics. Incomplete dominance occurs when the combination of two different alleles results in a phenotype that is intermediate between the two homozygous phenotypes. In this case, the combination of the red allele (R) and the absence of pigment allele (r) in the heterozygous offspring (Rr) produces a small amount of red pigment, giving the flowers a pink appearance.
