Summary

  1. 1.

    An investigation was carried out inDrosophila melanogasler to find out the effect of an unchanged chromosome II and changing the remaining chromosomes on the fecundity and hatchability. The stocks selected differed distinctly from each other in respect of both the traits. They were N-2 which was a normal wild type strain maintained in the laboratory and C-l containing a marked and completely balanced chromosome II obtained from outside.

  2. 2.

    Reciprocal crosses were made between N-2 and G-l Hies. Selecting F-l females with the marked chromosome in one case, repeated backcrosses were made with N-2 males from stock and in another case with C-l males. In each generation, the fecundity and the hatchability were noted.

  3. 3.

    Results showed that the chromosome II contained genes for fecundity and hatchability which were more than in all the other chromosomes put together.
