Associated with a pair of reciprocal transpositions that are tentatively postulated to result from a pair of inversions, one included within the other. Based on reversion analysis Sco postulated to result from the juxtaposition of noc+ and sna+ at the 34A5/35D1 junction.

Detailed Description
Statement
Reference

snaSco/+ flies lack the anterior scutellar and posterior scutellar bristles. The regular array of ommatidia in the eye is disturbed and the number of ommatidia is reduced by about 8.8%. The number of interommatidial bristles is reduced by 51.2%.

Heterozygotes show loss of 100-15 bristles on the thorax, the scutellars, notopleurals, upper humerals and anterior postalars being most frequently affected.

snaSco/+ flies have 25-27 dorsal head and thoracic bristles.

Genetic Interactions
Statement
Reference

snaSco enhances the small, rough eye phenotype caused by expression of HScer\UAS.cMa under the control of Scer\GAL4GMR.PU.

The snaSco/+ loss of macrochaetae phenotype is significantly enhanced by za, zae(bx) or z1.

Enhanced by nocTE35B; the number of dorsal head and thoracic bristles seen in snaSco/nocTE35B flies is reduced to approximately 16, compared to 25-27 in snaSco/+ flies.
