    In combination with other aberrations

    In(1)y3PLsc8R/Dp(1;Y)y+ embryos develop MP2 neuroblast normally.

    NOT in combination with other aberrations

    Has dominant 'Hw' effect that produces one or more humeral microchaetae in X/Dp(1;Y)y+ male and X/X/Dp(1;Y)y+ female and one or more hairs in the membrane of the second and third posterior cells of wing (Schultz) and extra veins, especially associated with the posterior crossveins (FBrf0019329) in X/Dp(1;Y)y+/Dp(1;Y)y+ males. y/Dp(1;Y)y+ males show some variegation for y without enhancers of variegation and considerable y variegation in the presence of E(var)7 and E(var)21 (FBrf0021939; FBrf0023019).

    Other Comments

    A cross between D.melanogaster Ts(1Lt;YLt)Zhr/Dp(1;Y)y+ males and D.sechellia females does not produce viable male progeny.

    Derivatives with mutant alleles of y have been recovered.
