A novel genetic interaction between daughterless and a variegating rearrangement strain of Drosophila melanogaster.
The effect of the maternal-effect mutation daughterless (da) on the reinverted In(1)BM2 strain of Drosophila melanogaster has been evaluated cytogenetically. Results show that while the variegated nature of the single X chromosome of In(1)BM2(rv) males born to female da/da x male +/+ parents is suppressed, their female sibs, homozygous for the In(1)BM2(rv) chromosome, survive the lethal effect of the absence of da+ product in their zygotes.
