alleles of different genes assort independently into gametes, giving the 9:3:3:1 dihybrid ratio.

In simple words: alleles of different genes assort independently into gametes, giving the 9:3:3:1 dihybrid ratio. Getting Independent assortment clear matters because NEET questions on Principles of Inheritance and Variation usually test this idea directly, not just a formula you memorised.
