Polytene chromosomes normal.
Deletion removes the entire iab-8 and iab-9 region of Abd-B.
Point mutation.
No Abd-B protein was detected in embryos.
denticle & embryonic abdominal segment 9 | somatic clone
sclerite & abdominal segment 8 & embryo | somatic clone
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.
Df(3R)P9/Abd-Biab8-D16 has lethal phenotype, suppressible by Dp(3;Y)JX3
Df(3R)P9/Abd-Biab8-D16, Dp(3;Y)JX3 has viable phenotype
Df(3R)P9/Abd-Biab8-D16, Dp(3;Y)JX3 has visible | somatic clone phenotype
Abd-Biab8-D16/Abd-Biab9-tuh-3, tuh1g has male genitalia phenotype
Df(3R)P9/Abd-Biab8-D16, Dp(3;Y)JX3 has abdominal segment 6 | somatic clone phenotype
Df(3R)P9/Abd-Biab8-D16, Dp(3;Y)JX3 has abdominal segment 7 | somatic clone phenotype
Abd-Biab8-D16, Scrhs.PZ has parasegment 1 phenotype
Abd-Biab8-D16, Scrhs.PZ has embryonic/larval salivary gland | embryonic stage phenotype
Abd-Biab8-D16, Scrhs.PZ has mandibular segment phenotype
Abd-Biab8-D16, Scrhs.PZ has parasegment 14 phenotype
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.
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.
Duncan.
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.
