    In combination with other aberrations

    Fails to complement Df(2L)Dwee1.

    NOT in combination with other aberrations

    The Df(2L)J-H 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).

    Heterozygosity for Df(2L)J-H results in 1.3% X chromosome nondisjunction and 0.6% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

    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 no maternal enhancement of dpphr4.

    Deficient embryos show an uninterpretable mutant midgut phenotype.

    resealing of chromosome 2 to create, strictly, a Tp(Y;2) that is also deficient for a segment of 2L.
