Chromosome catenation in someF 1 Oenothera hybrids


The chromosome linkages in a number ofOenothera F 1 hybrids have been found to show that (1) the chiasma frequency per pair of chromosome limbs is higher in the bivalents than in the multiple rings, (2) the pairs of frequencies in different hybrids are positively correlated, and (3) breaks (chiasma failures) occur at random in the rings.
