Summary We investigated the maturation divisions of two obligate parthenogenetic natural interspecific hybrids: the diploid B. whitei and the triploid B. lynceorum. B. whitei shows two maturation divisions which produce 4 viable haploid nuclei. At the telophase II two non-sister nuclei come into contact and fuse to restore the diploid chromosome number and the maternal genetic structure. On the other hand, in the triploid B. lynceorum, pachytenic oocytes undergo an extra DNA doubling which… Expand
