Early adjustment of patterns of metaphase association in the evolution of a polyploid species

Abstract

Evidence is presented for the adjustment of chromosomal association at metaphase in the very early stages of establishment of a new level of polyploidy. The species concerned is S. cambrensis Rossner, the hexaploid hybrid between S. squalidus L. (2n=20) and S. vulgaris (2n=40). It is suggested that the perfect bivalent pairing of S. vulgaris is the basis for the success of S. cambrensis.
