    In combination with other aberrations

    Df(2L)b84h1 in combination with Df(2L)k08712-rv21 do not exhibit a change in the frequency of single strand annealing.

    Df(2L)TE35B-7/Df(2L)b84h1 flies carrying Pgant35A+tGal show normal sensitivity to methyl methanesulfonate or γ rays. Df(2L)TE35B-7/Df(2L)b84h1 flies carrying Pgant35A+tGal show significantly greater microsatellite instability compared to control flies. Df(2L)TE35B-7/Df(2L)b84h1 flies carrying Pgant35A+tGal show a decrease in the stability of the dinucleotide repeat present in the wA87.2 allele when it is copied into the site of a double-strand break during gene conversion.

    NOT in combination with other aberrations

    Flies carrying both Df(2L)b84h1 and Df(2L)TE35B-7 are semi-sterile.

    The lethal phenotype of Pgant35A-/Pgant35A- and Df(2L)TE35B-7/Df(2L)b84h1 (with both Pgant35A and spel1 deleted) can be rescued by a fragment of genomic DNA that includes Pgant35A but not spel1.
