sta2/Y ; RpS21k16814/RpS21k16814 animals die as first to second instar larvae. sta2/Y ; RpS21k16814/+ and sta2/sta2 ; RpS21k16814/+ animals die as first to second instar larvae. sta2/+ ; RpS21k16814/RpS21k16814 third instar larvae are larger in size and have much larger overgrown imaginal discs than RpS21k16814/RpS21k16814 larvae. The leg discs tend to fuse together and the hematopoietic organs are larger than in RpS21k16814/RpS21k16814 larvae. The sta2/+ ; RpS21k16814/RpS21k16814 third instar larvae are more active than RpS21k16814/RpS21k16814 third instar larvae. The bristle phenotype of RpS21k16814/+ heterozygotes is enhanced by sta2; Dp(1;3)sta/+ or sta1/sta2.
in combination with variegating translocation (T(1;2)dorvar7) produces incised wing margins, small rough eyes with missing facets and missing head macrochaetae (Demakova and Belyaeva, 1988).
