Detailed Description
Statement
Reference

Abd-Biab8-D16/Abd-BFab7-1 males show a reduction in size of the seventh abdominal tergite to the size of the seventh abdominal tergite in Abd-BSz/+ males, however, the sixth abdominal tergite is larger in Abd-Biab8-D16/Abd-BFab7-1 males than in Abd-BSz/+ males and more closely resembles wild-type.

The Abd-Biab8-D16/Df(3R)P9 combination is lethal, and clones of Abd-Biab8-D16/Df(3R)P9 show no male specific pigment in abdominal segments.

Homozygotes die as late embryos or early first instar larvae. Embryos have no posterior spiracles.

Heterozygotes with Abd-Biab9-tuh-3 exhibit genital defects.

A5-A8 (including female genitalia) transformed to A4 in mosaics. Embryos have sclerotic plates in pA8 and occasional extra denticles in A9, and parasegments 10-13 are transformed to parasegment 9.

Statement
Reference

Mutant phenotype of Abd-Biab9-tuh-3/Abd-Biab8-D16 responds to tuh1g maternal effect by producing genital defects.

Dp(3;Y)JX3; Abd-Biab8-D16/Df(3R)P9 flies are fully viable and show male specific pigment in A6 and A7.

In the presence of construct P{HS-Scr.Z} ectopic salivary glands form in parasegments 0, 1 and 14.

Comments

Abd-Biab8-D16 does not complement the iab-7 loss of function mutant Abd-BSz in segment A7 in males.

Fails to complement all mutations in the Abd-B domain.

Strong allele.

Fails to complement all mutations in the Abd-B domain.

Embryos lack Abd-B protein, this correlates with the loss of both the m and r genetic functions.

m- r- Abd-B mutation.

Genetically null for the Abd-B m function.

Abd-B m-r- mutation.
