hypomorphic allele - genetic evidence
viable
dorsocentral bristle
mesothoracic cleft
Heterozygotes with Df(3R)sbd45 are viable with strong thoracic cleft defects and loss of bristle. Heterozygotes with other pnr alleles are viable. Heterozygotes with pnrD4 exhibit variegating position effect.
Class 1 pnr allele: viable recessive allele.
