Mutants are lethal from late embryonic to second instar larval stages. A slight defect in the head skeleton is seen - the dorsal bridge is distorted.
hrgPAP21/hrg[+] is an enhancer of visible phenotype of Hsap\PABPN117ala.Act88F
hrgPAP21/hrg[+] is an enhancer of lethal | embryonic stage | maternal effect phenotype of orbmel
hrgPAP21/hrg[+] is an enhancer of wing phenotype of Hsap\PABPN117ala.Act88F
The percentage of maternal effect embryonic lethality seen in embryos derived from orbmel homozygous females is increased by heterozygosity for hrgPAP21. The percentage of ventralised embryos is increased by heterozygosity for one copy of hrgPAP21.
Oogenesis is blocked at stage 8 in 34% of hrgPAP21/+ ; orbmel females.
hrgPAP21 enhances the wing posture defects seen upon expression of Hsap\PABPN117ala.Act88F.
Phenotypic analysis suggests the following allelic series: hrgPAP12 > hrgPAP21 > hrgPAP45.
