Homozygous gfzfSu(Kpn)1, or trans-heterozygous gfzfSu(Kpn)1/gfzfSu(Kpn)2, mutants are lethal at the embyro/first larval instar interphase. They also exhibit an autonomous small imaginal disc phenotype.
gfzfSu(Kpn)1 is unable to suppress the lethal interaction between pn18a and endogenous awdK.
When females that are homozygous for pn18a and heterozygous for gfzfSu(Kpn)1 are crossed with males homozygous for awdK, no males that are hemizygous for pn18a, heterozygous for gfzfSu(Kpn)1, and heterozygous for awdK are recovered. In contrast, hundreds of female progeny that are heterozygous for pn18a, heterozygous for gfzfSu(Kpn)1, and heterozygous for awdK are recovered.
gfzfSu(Kpn)1 can suppress the lethal interaction between pn18a and transgenic awdKpn.cPa.
When females that are homozygous for pn18a and heterozygous for gfzfSu(Kpn)1 are crossed with males homozygous for the transgenic awdKpn.cPa, hundreds of both female and male progeny that are hetero/hemi-zygous for pn18a, and heterozygous for gfzfSu(Kpn)1, and heterozygous for awdKpn.cPa are recovered. The ratio of males to females is 0.65, indicating suppression of the awdKpn.cPa 'Killer of prune' phenotype.
Based on the extent of suppression of pn18a-awdKpn.cPa lethality, the following gfzf alleles can be ranked from the strongest to the weakest as follows: gfzfSu(Kpn)2 > gfzfBU640 > gfzfDC727 > gfzfAP320 > gfzfCK438 > gfzfCZ811 > gfzfSu(Kpn)1 > gfzfAP434 > gfzfCX322 > gfzfBX123 > gfzfBW914 = gfzfAB621 > gfzfSu(Kpn)3 > gfzfBS304 > gfzfCU338 > gfzfDC806 = gfzfCL1027 > gfzfAV739 > gfzfAB924.
