The Df(3L)81k19 chromosome does not act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).
Causes inviability or low viability in hybrid females when heterozygous with D.simulans chromosome.
Strong second site non-complementing phenotype with zipEbr and zipmhc-c6.1 : malformed phenotype penetrance >75%.
Shows no maternal enhancement of dpphr4.
P{hs-Eip78C-B} expression in heterozygotes causes a reduction in the 63E, 71CD and 82F late puffs and the 62E early/late puff.
Midgut development of mutant embryos is wild type.
Homozygous embryos show abnormal head involution, germband retraction and dorsal closure. Midgut constrictions do not form and Malpighian tubules are not completely elongated.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
