In a dihybrid cross involving two genes with supplementary gene interaction, the expected phenotypic ratio of the F2 generation is 15:1. This ratio results from the interaction of the recessive alleles of both genes being required to produce the novel phenotype. Hence option D is the correct answer.

Option(A) In a dihybrid cross involving two genes with supplementary gene interaction, the expected phenotypic ratio of the F2 generation is 15:1. Hence option A is incorrect.

Option(B)  In a dihybrid cross involving two genes with supplementary gene interaction, the expected phenotypic ratio of the F2 generation is 15:1. Hence option B is incorrect.  

Option(C)  In a dihybrid cross involving two genes with supplementary gene interaction, the expected phenotypic ratio of the F2 generation is 15:1. Hence option C is incorrect.
