Answer:
50%
Explanation:
Given that the genotype of the pink-flowered parent plant is "Rr" and that of the red-flowered parent plant is "RR"; the cross between heterozygous pink and homozygous red-flowered snapdragon plants obtain progeny in the ratio of 1 red: 1 pink.
The genotype ratio for the progeny is= 1 RR (homozygous dominant) : 1 Rr (Heterozygous dominant).
