parasegment 10 (with Df(3R)Abd-BS10)
parasegment 11 (with Df(3R)Abd-BS10)
parasegment 12 (with Df(3R)Abd-BS10)
ventral denticle belt (with Df(3R)Abd-BS10)
Heterozygous males have a 7th tergite and the 6th sternite has bristles. Homozygous females have no 8th tergite.
Abd-BS12/Df(3R)Abd-BS10 embryos have Abd-B mutant phenotype: denticle belts of parasegments 10-12 resemble that of parasegment 9.
