Summary
The phenomenon of male recombination has been found in more than twenty per cent of lines derived from wild-caughtDrosophila melanogaster. The recombination appears to be caused by a factor which is attached to, and transmitted with chromosomes, but which is readily transposed to other chromosomes. The possibility exists, however, that the factor is also capable of independent existence in the nucleoplasm. Extensive testing indicates that the factor is not contagious. The factor has been named “Male Recombinant Factor” or “MRF”.
