Frequency of microchaetae defects in myt1 and wee1/+; myt1 mutants

Genotype	2 Sha., 1 Soc.	1 Sha., 2 Soc.	2 Sha., 2 Soc.	0 Sha., 1 Soc.	Total bristles	Normal bristles	Total defects	% Defective

Microchaetae are small bristles, found on most of the adult cuticle, with a single shaft and a single socket. These are normal in myt1¹/myt1¹ single mutants but exhibit defects in wee1/+; myt1¹/myt1¹ mutants. To quantify these defects, all of the microchaetae were scored within the area bounded by the four central thoracic macrochaetae on the scutum of 10 males and 10 females of each of these genotypes. Sha., shaft; Soc., socket.
