0biology :(?

Your friend, Nancy, works at a local nursery. You mention that you have been learning about genetics. She then asks you, "Why are all the offspring pink when I cross the red snapdragons with white snapdragons?" You tell Nancy this is a result of __________.








a. a sex-linked trait





b. incomplete dominance





c. codominance





d. dominance

Incomplete dominance





This refers to blending of traits, while codominance refers to both being expressed for example as striped flowers. They are similar in that both produce a third phenotype.
Reply:e. my stupidity :-(
Reply:I am assuming co dominance because both colors are equally present.
Reply:incomplete dominance. this mixes the colors to produce a different color.
