Question

if mendel had crossed a true breeding dominant plant with a true breeding recessive plant, in which of the three generations is the recessive trait visible?
○ f₁ generation only
○ p generation only
○ f₁ generation and f₂ generation
○ p generation and f₂ generation

Explanation:

• P generation: True - breeding recessive plant shows recessive trait.
• F₁ generation: Offspring of dominant (PP) and recessive (pp) parents are all Pp, showing dominant trait.
• F₂ generation: When F₁ (Pp) self - cross, offspring have genotypes PP, Pp, pp. pp shows recessive trait. So recessive trait is visible in P and F₂ generations.

Answer:

D. P generation and \( F_2 \) generation
