If a cross between f2 and f3 produces a bell-shaped curve distribution, which type of inheritance is most likely

If a cross between f2 and f3 produces a bell-shaped curve distribution, which type of inheritance is most likely shows quantitative inheritance.

We know that i we cross a tall and short pea plant and have a look on F2 generation, we can say the genotype and phenotype of both short and tall plants. These type of traits are called discrete or discontinuous traits.

Continuous traits are frequently measured and given a quantitative value so they are often referred as quantitative traits which shows normal distribution or bell shaped curve distribution.

the answer is a or when it says crossing over

b a mature ovary of a plant.
