    In combination with other aberrations

    Fails to complement Df(3L)ZP1.

    Df(3L)66C-G28/Df(3L)pbl-X1 lethal (Jeanette Natzle)

    NOT in combination with other aberrations

    Df(3L)66C-G28 embryos show defects in tracheal cell migration.

    The Df(3L)66C-G28 chromosome acts as a dominant moderate 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).

    Little if any macrophage migration occurs in homozygous embryos, with most macrophages remaining in the anterior region, clustered around the foregut, at stage 13-15.

    Heterozygosity for Df(3L)66C-G28 results in a high but variable degree of X chromosome nondisjunction (23.3% and 25.8% in two separate experiments) and fourth chromosome nondisjunction (12.7% and 25.0% in two separate experiments) in In(1)FM7/X ; svspa-pol females. Recombination frequency along the length of the third chromosome does not show significant deviation from normal in females carrying a multiply marked third chromosome and Df(3L)66C-G28.

    Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.

    No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

    Shows maternal enhancement of dpphr4, dpphr56 and dpphr27, measured as reduction in recovery of doubly heterozygous progeny.

    Midgut development of mutant embryos is wild type.

    Used in D.melanogaster/D.simulans hybrids to map at least four non-overlapping regions on the D.simulans 3R that have effects on the species difference of cuticular hydrocarbon profile.
