The control of chiasma formation in colchicine treated meiocytes of Senecio squalidus.
Colchicine induced multivalent formation is used to examine the effects of multivalent formation on chiasma frequency in Senecio squalidus. The increases observed are interpreted as the results of increases in numbers of pairing segments or decreases of chiasma interference following pairing partner exchange.
