    In combination with other aberrations

    The lethality of the Df(1)LCD chromosome is not complemented by Dp(1;f)LJ9.

    Dp(1;f)LJ9/FM7 males variegate for g (Schalet) Dp(1;f)LJ9/In(1)dl-49, y m2 g4 males variegates for g (Schalet) Dp(1;f)LJ9/C(1;Y)2, In(1)EN, Df(1)gl, y, g, f, B males viable (Schalet) Dp(1;f)LJ9/C(1;Y)2, In(1)EN, Df(1)gl, y, g, f, B males fertile (Schalet)

    NOT in combination with other aberrations

    Two copies of Dp(1;f)LJ9 can be lethal due to an included male diplo-lethal region.

    g[+], ty[+] and na[+] expression is imprinted in response to the sex of the parent. For example, eyes of flies heterozygous for g53d/Dp(1;f)LJ9 depend on parental derivation of Dp(1;f)LJ9 chromosome. Eyes show variegation if Dp(1;f)LJ9 derived from male parent, and not if Dp(1;f)LJ9 derived from female parent. These variegating phenotypes persist for one generation only, i.e. is reset by passage through the germ line. The imprint is a response to the physiological sex of the parent, and does not depend on the particular allele of g opposite Dp(1;f)LJ9. Factors that affect position effect variegation influence the somatic expression but not the establishment of the imprinting.
