Minute phenotype and haplo sterile. Weak head defects, wrinkled dorsal epidermis and internalised and often disorganised filzkorper. Female transheterozygotes with tkv1 are viable and display a wing vein phenotype, some wing vein thickening. Transheterozygotes with tkv4, tkv5 and tkv7 display extremely thickened veins and heterozygotes with tkv6 display wing veins that are very thick and short along the proximal distal axis. Adult Df(2L)tkv3/tkv8 females are very weak, possess atrophic ovaries and do not lay eggs in the few days they survive beyond eclosion. Adult Df(2L)tkv3/tkv7 females lay eggs, embryos from these females crossed to wild type males die showing a moderately ventralised phenotype. Adult Df(2L)tkv3/tkv6 females lay eggs, some of the embryos from these females crossed to wild type males die showing a weakly ventralised phenotype.
Sterile and reduced viability.
Homozygous lethal, shows a strong Minute phenotype. Dominant female sterility and males are not completely sterile. Chromosome does not have a suppressor effect on w variegation of In(1)wm4h.
Females sterile; males semisterile.
