Abstract

PROF. R. GOLDSCHMIDT describes two cases of spontaneous mutations in Drosophila cultures in which three well-known mutants, and possibly five, were produced by intra-chromosomal rearrangement. The observed mutations, the author states, do not agree with the theory postulating the existence of genes or gene mutations ; he would explain mutations as due to changes in the 'correct order' within the chromosome chain, without attaching particular characters to special regions of the chromosome.
