P484S | vn-PA; P484S | vn-PC
Polytene chromosomes normal.
Amino acid replacement: P483S. Nucleotide substitution: C?T.
lethal | heat sensitive
vnC221/vnddd-13 transheterozygotes are semi-viable at 25oC, escapers survive for 3 days and are of normal appearance except for held-out wings and the absence of anterior cross vein.
Individuals transheterozygous with a strong EMS vn mutation at 20oC exhibit held out wings, at 27oC individuals are prepupal lethal with notumless wing discs.
Heteroallelic combinations cause smaller wings, in addition to gaps in wing veins.
