Description	The physical basis of non-Mendelian segregation of a sex-linked marker was studied in sex- chromosome mutant females of eight ASF ('abnormal segregating females') lines in the flour moth, Ephestia kuehniella. Electron microscopical analysis of microspread synaptonemal complexes revealed that meiotic pairing of Z-chromosome fragments is responsible for the atypical segregation. In two ASF lines, the fragment contains a piece of the W chromosome (shown by comparative genomic hybridization, CGH) which acts as a male killing factor. Finally, this study provides direct evidence for the regular transmission of radiation-induced fragments from lepidopteran chromosomes through more than 50 generations.
