SummaryThe correspondence between the number of metaphase I associations (bonds) and the chiasma frequency of specific chromosome arms of rye has been analysed in the meiosis of Triticale-rye hybrid plants. These plants were heterozygous for prominent telomeric C-bands in the two arms of chromosome 1R. From the frequency of bound arms at metaphase I and the frequency of recombined chromosome at anaphase I in the arms considered, estimates of chiasma frequency can be made under the assumption… CONTINUE READING

The discrepancy between metaphase I and anaphase I results , due to an excess of anaphase I parental chromosomes , can be explained on the assumption that some of the bonds appearing at metaphase I are achiasmate and a remnant of prophase pairing .
