X chromosome nondisjunction in solo females.

aDp(1;1)scv1, y pn cv m f.y+/y females of the indicated chromosome 2 genotypes were crossed with YSX.YL, In(1)EN, y B/Y males (X∧Y/Y). Df = Df(2L)A267 that is deficient for solo.bDJ = normal (disjunctional) progeny.cH = Matriclinous daughters derived from homolog NDJ.dS = Matriclinous daughters derived from sister chromatid NDJ. See Figure S1 for classification of NDJ types.eN = total number of progeny.Since there was no significant difference among the three controls, the numbers were summed for the analysis.f%NDJ = 100×2×NDJ flies/(N+NDJ flies) where NDJ flies = (H+S+nullo).g%S = 100×S/(S+H).hP/F = mean progeny per female.
