In snapdragons, flower color shows incomplete dominance. A cross between a pink-flowered plant and a white-flowered plant will produce offspring in the ratio of:
- A.
- B.
- C.
- D.All pink
Show correct answer & step-by-step solution
Correct answer: B —
Solution
- Let be red and be white. Pink is .
- The cross is (pink) (white).
- The offspring genotypes are $1 Rr$ and $1 rr$.
- This results in a phenotypic ratio of pink : white.
- Hence the answer is (B).
