(D) Dominant epistasis is a gene interaction where a dominant allele at one locus masks the expression of alleles at another locus.It is typically observed in $Cucurbita 	ext{ } pepo$ (summer squash), where the fruit color is determined by the interaction of two gene loci.$Antirrhinum 	ext{ } majus$ exhibits incomplete dominance.$Lathyrus 	ext{ } odoratus$ exhibits complementary gene action.$Mirabilis 	ext{ } jalapa$ exhibits incomplete dominance.Therefore, none of the given options represent dominant epistasis.
