Abstract
On the assumption that the breakages and recombinations occur at random, a generalized expression for calculating the expected ratio of rings and pseudo-isochromosomes in any given organism was derived. Results from the comparisons of observed data for barley and maize with the theoretical except in two cases indicate that the interchanges between chromosomes, homologous or non-homologous, were random.
