If a pure tall plant is crossed with a pure dwarf one, the ratio of tall pure dwarf in the F 2 generation after selling F1 plant will be___________________?
Correct answer: B. 1:1
- A. 1:2
- B. 1:1
- C. 2:1
- D. 3:1
Explanation
The cross TT × tt produces all Tt tall plants in F1; selfing them gives F2 genotypes TT:Tt:tt = 1:2:1. Thus pure tall TT to dwarf tt is 1:1.
