title: [Frequency of radiation-induced exchanges in easily identifiable monkey chromosomes].
abstract: Frequency of asymmetric exchanges of readily identifiable chromosomes 1, 2, 3, 4, 8, 9 ad 20 was studied in primary kidney cell cultures of monkeys. Macaca mulatta and Papio hamadryas irradiated with 200 R of X-rays at G0. The chromosomes studied enter asymmetric exchange in accordance with their lengths of mitosis. The frequency of exchanges is independent of the quantity of late-replicating heterochromation in chromosomes. The radiosensitivity of chromosomes was identical in the two monkey species.
