TrpRS[+]/TrpRSP-74 is an enhancer of partially lethal | maternal effect | female phenotype of Sxl[+]/SxlfP7B0, snfJ210
The weak interaction between SxlfP7B0 and snfJ210 is enhanced by Aats-trpP-74; the viability of female SxlfP7B0/+ embryos derived from mothers heterozygous for snfJ210 and Aats-trpP-74 is reduced.
