A set of ~50 targeted deficiencies created by exploiting hybrid element insertion (HEI) and resolution; designed to fill gaps in deletion coverage.
21C3-21C4;21C6-21C8
Lethal in combination with Df(2L)ast2.
The Df(2L)BSC16 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).
The miniwhite marker from P{lacW}exk12913 was deleted or disrupted.
