X chromosome nondisjunction in <i>solo</i> 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.
