male fertile, with lark1
lark1 animals rescued by larkRRM2.RNP2.T:Ivir\HA1 have scutellar bristle defects (50-100% penetrance) and a "held out" wing phenotype (48-100% penetrance). lark1 homozygotes carrying larkRRM2.RNP2.T:Ivir\HA1 show normal eclosion rhythms in 12 hour light:12 hour darkness conditions and normal free-running eclosion rhythms.
