Answer:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white
Step-by-step explanation:
This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.
According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white
