For a poly hybrid cross concerning N trait, what is the number of squares required in the Punnett square to check for the F2 generation?

For a poly hybrid cross concerning N trait, what is the number of squares required in the Punnett square to check for the F2 generation? Correct Answer 2(2N)

For a poly hybrid cross involving N traits, according to the law of independent assortment, 2N types of gametes will be produced by each parent. Therefore, the cross of these progeny will give (2N)*(2N) = 2(2N).
