The Ecol\lacZ gene of the progenitor P{Abd-B-lacZ.Fab-8.iab-8}Abd-Blac1 insertion is retained but the ry sequences have been disrupted.
adult abdominal segment 4 | ectopic | male (with Df(3R)P9)
testis (with Abd-Biab8-D14)
In Abd-Biab8-D14/Abd-BT2N mutant females (mutant for Abd-B m protein), the internal female genitalia do not develop properly and, in some cases, parovaria are the only structures remaining. In males, these mutants do not affect the internal genitalia, although the testes are reduced in size and are not connected properly with the internal genitalia.
