6% of the eggs (n=112) laid by kek1Scer\UAS.P\T.cGa; Scer\GAL4nos.UTR.T:Hsim\VP16 females are weakly ventralized (partial or total fusion of the dorsal appendages).
Scer\GAL4VP16.nanos.UTR, kek1UASp.cGa has dorsal appendage phenotype, enhanceable by grk2B6/grk[+]
Scer\GAL4VP16.nanos.UTR, kek1UASp.cGa has egg phenotype, enhanceable by Egfr[+]/Egfrt1
The penetrance and expressivity of the weak ventralization phenotype seen in eggs laid by kek1Scer\UAS.P\T.cGa; Scer\GAL4nos.UTR.T:Hsim\VP16 females is strongly enhanced by heterozygosity for Egfrt1 (64% of eggs are ventralized, 8% strongly ventralised) or grk2B6.
