Question

A snapdragon with pink flowers with the genotype Rr is mated with a snapdragon with red flowers with the genotype RR. What is the possibility of obtaining a flower with a heterozygous genotype?
The possibility of obtaining a heterozygous flower is __%

Answer 1

you should draw a punnet square and get 50% heterozygous

Answer 2

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).
