The B-chromosomes of Tainia laxiflora behaved regularly like the ordinary chromosomes in both meiotic division of PMC and in the successive mitotic divisions. As a result, most of the male gametes are presumed to carry the B-chromosomes. The regular meiotic and mitotic behavior of B-chromosomes is considered to be a major cause of the high occurrence of the clones with B-chromosomes in this species.
