The 3R:5632351 release 6 coordinate of the left breakpoint is an estimate. It corresponds to the insertion site of P{EP}CG31549^EP3625. Df(3R)BSC47 was generated by expression of P transposase in the presence of trans-heterozygous P elements. Since the deletion chromosome did not retain the miniwhite marker from either progenitor P insertion, it was probably formed by nonhomologous end joining of breaks near the insertion sites of the progenitor P insertions. Df(3R)BSC47 heterozygotes do not show Minute phenotypes, so the haploinsufficient RpL13A gene lies to the left of this breakpoint.

The 3R:5861298 release 6 coordinate of the right breakpoint is an estimate. It corresponds to the insertion site of P{EP}CG2017^EP3503. Df(3R)BSC47 was generated by expression of P transposase in the presence of trans-heterozygous P elements. Since the deletion chromosome did not retain the miniwhite marker from either progenitor P insertion, it was probably formed by nonhomologous end joining of breaks near the insertion sites of the progenitor P insertions.

Only the distal tip of the salivary gland turns in embryos homozygous for Df(3R)BSC47 by stage 14.

The Df(3R)BSC47 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{w^var}KR3-2", a stable "brown-red" variant of the P{3'WP-2,w^var}2Lt insertion).
