Fig. 6. Su(lyh) dominantly suppresses da^lyh phenotypes, both loss- and gain-of-function. (A-D) DAPI-stained ovaries. The da^lyh loss-of-function phenotype (A) is completely suppressed by a single copy of Su(lyh) (B) (genotype, da^lyh/da^lyh; Su(lyh)26H6/Su(lyh)+). The da^lyh-associated gain-of-function phenotype (C) (genotype, Tp(2;Y)da⁺; da^lyh/da^lyh) is also dominantly suppressed by Su(lyh)26H6 (D). Note that the reduced germaria (asterisks) that characterize the da⁺ overexpression phenotype are not present in the ovaries that carry the suppressor genotype.
