title: Recombination in Drosophila melanogaster male.
abstract: T-007 strain of Drosophila melanogaster is known to show recombination in males. The present study established the following points: (1) Clustering occurrence of recombinant, unequal recovery of complementary products of recombination, relatively high frequency of recombination around centromeric region, and relatively frequent occurrence of mosaic phenontype flies-all of these seem to indicate that a considerable fraction of male recombination in the T-007 strain is of premeiotic, or somatic origin, although a fraction still could be of meiotic origin; (2) Male recombination occurs in the third as well as in the second chromosomes, and the frequencies of recombinations are comparable between these two chromosome pairs.
