Which of the following may be used to obtain an F₂ generation?(a) allowing flowers on a parent plant to be self-pollinated(b) allowing flowers on an F₁ plant to be self-pollinated(c) cross-pollinating an F₁ plant with a parent plant(d) cross-pollinating two parent plants

Correct Answer: (b) allowing flowers on an F1 plant to be self-pollinated

Explanation:

F1 generation of the plant is obtained when pure dominant and pure recessive parent plant is allowed to be cross-pollinated.

F2 generation of the plant is obtained when flowers on an F2 plant are allowed to undergo self-pollination.
