A homozygous translocation in Drosophila melanogaster
Five cases of translocation involving the third and the fourth chromosomes of Drosophila melanogaster have been found in the progeny of flies treated by x-rays. The flies carrying a given translocation seem to be perfectly normal in their appearance, but, when tested genetically, they show linkage of genes belonging to the third with genes belonging to the fourth linkage group.

Independently Muller and Painter have come to similar results on the basis of study of numerous translocations obtained by them in Drosophila (Muller and Painter, 1929).
