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 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, 1967Experiments 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.

SummaryThe study of crossing‐over leads us on the one hand to consideration of the physio‐chemical nature and behaviour of the chromosomes, and, on the other to conclusions respecting the better‐known phenomena of segregation, pairing, recombination and gene action. Although many aspects of the cause and consequence of crossing–over are still not fully

Imagine you had a choice between only two investments: stocks and bonds. Which would you choose? Investors in bonds are conservative, seek stable income and have a longer-term investment horizon. Investors who purchase stocks are “aggressive” and want high returns in a shorter period of time.
