Polytene chromosomes apparently normal (Schultz).
More than 90% of flies lack the anterior notopleural, postvertical, ocellar, scutellar and anterior orbital bristles. The humeral, presutural, anterior postalar, anterior supraalar, posterior postalar and posterior supraalar bristles are present.
More than 90% of scD1 flies lack the anterior orbital, post-vertical, ocellar and anterior notopleural bristles. The flies have one scutellar bristle.
Anterior notopleural bristle formation is blocked.
Phenotype can be suppressed by strong su(Hw) alleles, or weak su(Hw) alleles in combination with mod(mdg4)ul. mod(mdg4)ul has a partial suppressing effect alone.
Weak sc. RK2.
Homozygous females show a loss of tergite chaetae.
scD1 has visible phenotype, enhanceable by Df(1)260-1
mod(mdg4)ul, scD1 has visible | recessive phenotype, suppressible by Su(mg)1-71-7
scD1 has visible | recessive phenotype, suppressible by mod(mdg4)ul
scD1 has chaeta phenotype, enhanceable by Df(1)260-1
scD1 has tergite phenotype, enhanceable by Df(1)260-1
scD1 has anterior orbital bristle phenotype, suppressible by mod(mdg4)ul
scD1 has postocellar bristle phenotype, suppressible by mod(mdg4)ul
scD1 has ocellar bristle phenotype, suppressible by mod(mdg4)ul
scD1 has scutellar bristle phenotype, suppressible by zv77h
scD1 has anterior notopleural bristle phenotype, suppressible by zv77h
scD1 has ocellar bristle phenotype, suppressible by zv77h
scD1 has postocellar bristle phenotype, suppressible by zv77h
scD1, y2/y1#8 has adult cuticle phenotype
scD1, y59b/y2 has adult cuticle phenotype
The presence of sc[D1] in y2 scD1/y59b flies abolishes interallelic complementation. y2 scD1/y59b females show weak pigmentation of the body and wings.
The presence of sc[D1] in y2 scD1/y1#8 flies abolishes interallelic complementation. y2 scD1/y1#8 females show weak pigmentation of the body and wings.
The scD1 bristle phenotype is partially suppressed by mod(mdg4)ul.
