Abstract
B-chromosome systems in several Spanish natural populations of Eyprepocnemis plorans are reported. The geographical distributions of the fourteen types of B chromosomes, which were classified according to size, C-banding pattern, and meiotic behaviour, are described. The results indicate a common origin for most types and a possible independent origin for a few secondary B variants. The origin and mechanisms of evolution of this B chromosome polymorphism are discussed.
