Extract

The problem of viability and fertility of interspecific hybrids in Drosophila has been attacked most recently by Muller and Pontecorvo (1941). They crossed diploid Drosophila simulans males with triploid melanogaster females, and, by using a specially designed technique, succeeded in introducing into the marked genotype of melanogaster some chromosomes of simulans. Amongst the many interesting results obtained, it was found that not all interspecific combinations of chromosomes were viable; the large chromosomes of one species show a definite “need” for some genes or group of genes in other chromosomes of the same species, and these authors have drawn the conclusion that there are a number of complementary “lethals” in both species located in the major chromosomes (X, II, and III).
