[Comparison of frequencies of complete and incomplete translocations induced in mature sperm of Drosophila].
A frequency of induction of translocations taking place in mature sperm of Drosophila between heterochromatic portions of the 2L compound and 2R acrocentric was estimated to be 9.62 X 10(-3). This value is being compared with the previously estimated frequency of incomplete translocations in this system which is (2.5-2.9) X 10(-3). The ratio of frequencies of complete and incomplete translocations obtained was intermediate between the Panshin data, on the one hand, and those of Muller and Hershkowitz, on the other. The reasons for these discrepancies are under discussion. Based on the value obtained for this ratio, the probability of reunion of chromosome break (q) is calculated to be 0.79.
