Complex inversion that breaks within the pnt1277 P-element rendering the w+ gene defective but Ecol\lacZ intact but up-regulated.
lethal - all die during embryonic stage | recessive
some die during embryonic stage | recessive
Strong pnt allele. Allelic series of pnt allele that affect the P2 transcript: pnt1277 < pnt1202 < pnt1208 < pnt1230 <= pntT9 < pntT5.
