What is Mendel’s formula for determining the number of different types of genotypes in the F2 generation? (RJ Pre PG 2019)

✅Explanation:Mendel's formula 3^n determines the number of different types of genotypes in the F2 generation, where 'n' represents the number of segregating gene pairs. For example, in a dihybrid cross (two gene pairs), there would be 3^2 = 9 different genotypes.

📌Other Options Explanations:
-Option A (n): This formula simply represents the number of segregating gene pairs.
-Option B (2^n): This formula calculates the number of possible gametes from an individual with 'n' segregating gene pairs.
