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.
已知黑腹果蝇的T - 007品系在雄性中会发生重组。本研究确定了以下几点：（1）重组的聚集发生、重组互补产物的不均衡回收、着丝粒区域周围相对较高的重组频率以及嵌合表型果蝇的相对频繁出现——所有这些似乎都表明，T - 007品系中相当一部分雄性重组是减数分裂前或体细胞起源的，尽管仍有一部分可能是减数分裂起源的；（2）雄性重组发生在第三条染色体以及第二条染色体上，并且这两对染色体之间的重组频率相当。
