Homozygotes show little or no embryonic lethality. 16% lethality is seen during larval development, but the majority of the lethality occurs during early pupal and pharate adult stages. Some homozygous adults are able to eclose, but they die 2 to 3 days later. Homozygous pharate adults have malformed legs which are both short and bent. The basitarsus may be short and thick and the tibia may contain bends. 65% of mutant mid-prepupae have at least one malformed leg, 97% of mutant pupae and adults have at least one malformed leg.
Separable from: P{PZ}wek05271a. The P{PZ}wek05271a insertion is viable and fertile with no obvious defects in combination with deficiences covering the site of the P{PZ} insertion, indicating that the phenotype of the "l(2)05271" line (caused by l(2)05271b05271b) is separable from the P{PZ}wek05271a insertion.
