Question
Plants with how many genotypes will be available in the F₁ generation when a cross is made between two hybrid tall (Tt) plants ?
- One type
- Two types
- Three types
- Four types.
Answer
Two types
Explanation:
When two hybrid tall plants (Tt) are crossed, the genotypes in the F₁ generation will be TT (tall) and Tt (tall), each occurring in equal proportion. Therefore, there will be two genotypes in the F₁ generation.
