In a standard dihybrid cross involving two independent genes, the expected F2 phenotypic ratio is 9:3:3:1. A test-cross with an F1 individual and a double recessive usually yields a 1:1:1:1 phenotypic ratio if the genes assort independently.

In a specific cross, F2 progeny exhibit a modified dihybrid ratio of 15:1 (instead of 9:3:3:1).
