Chemistry of Crossing-over

Nature, 1967
The frequency of second division segregation of ascospore colour markers was used to demonstrate the effect of two chemicals (chloramphenicol and 5-fluorodeoxyuridine) on crossing-over in Neurospora. The effects of 5-fluorodeoxyuridine show that an impairment of DNA synthesis increases crossing-over.

Secondary Crossing-over

Nature, 1967
Secondary crossing-over between alleles seems to arise as a consequence of modifications of the normal crossover mechanism caused by a particular mutation. Interference between crossovers is believed to be polarized in relation to the centromere, but secondary crossovers are thought not to interfere with one another.

Crossing-Over and the Centromere

Cytogenetic and Genome Research, 1967
Experiments with human lymphocytes and H.Ep.2 human neoplastic cells treated with tritiated thymidine yielded evidence which suggests that sister chromatid crossing-over may occur in the centromere. As a result of this study a possible mechanism of isochromosome formation is postulated.
