Abstrakt: Frequency and position of chiasmata at diplotene were studied in pollen mother cells and megaspore mother cells of the same plants of two wild Allium species ( A. consanquineum and A. kachrooi) and two cultivated species ( a. cepa and A. nigrum), all diploid with 2n=16. Contrary to most reports on sex differences in recombination, chiasma frequencies were higher in male than in female meiosis in all cases. Chiasmata were non-localised except in A. kachrooi megaspore mother cells where they were proximally localised. [ABSTRACT FROM AUTHOR]
