GENETICS
Incomplete Dominance
1. In rabbits, neither black fur nor white fur is dominant. Cross a male
gray rabbit (BW) with a female white rabbit (WW). What are the
possible phenotypes of the offspring?
B=
W=
BW=
Phenotypes:
2. In snapdragons, the color of the petals is an example of incomplete
dominance. Cross a male red snapdragon with a female white
snapdragon and give the phenotypes and genotypes of the offspring.
RR x WW
Key:
Phenotypes:
(include percent)
Genotypes:
3. Use the key from question #2 and make a Punnett square to predict
the phenotypes of the offspring when crossing a red snapdragon
with a pink snapdragon?
