This assertion is true, but the reason given is incorrect. TSupplementary gene interaction occurs when two or more genes work together to produce a phenotype that cannot be produced by any of the genes individually. However, in this type of interaction, it is the recessive alleles of both genes that are required to produce the novel phenotype, not the dominant alleles as stated in the reason. Hence option B is the correct answer.

Option(A) Both assertion and reason are true and the reason does not explain assertion correctly. Hence option A is incorrect.

Option(C) Both assertion and reason are true and the reason does not explain assertion correctly. Hence option C is incorrect.  

Option(D) Both assertion and reason are true and the reason does not explain assertion correctly. Hence option D is incorrect.
