1. a. Red snapdragon: Genotype RR, Phenotype red
b. Pink snapdragon: Genotype Rr, Phenotype pink
c. White snapdragon: Genotype rr, Phenotype white
2. a. pink × pink
Genotypic ratio: 1 RR : 2 Rr : 1 rr
Phenotypic ratio: 1 red : 2 pink : 1 white
b. red × white
Genotypic ratio: 4 Rr
Phenotypic ratio: 4 pink
c. pink × white
Genotypic ratio: 2 Rr : 2 rr
Phenotypic ratio: 2 pink : 2 white
3. a. genotype: 1 HH : 2 Hh : 1 hh
phenotype: 1 horned : 2 hornless : 1 horned
b. genotype: 2 Hh : 2 hh
phenotype: 2 hornless : 2 horned
c. genotype: 4 Hh
phenotype: 4 hornless
4. The maximum number of phenotypes in the short amount of time would be 3 (red, pink, white).
