Abstract
THE latest annual report of Dr. C. B. Davenport 1 for the Department of Genetics at Cold Spring Harbor is contained in Year Book No. 33 of the Carnegie Institution of Washington for 1934. It covers the usual wide range of investigations bearing on genetics in plants, animals and man. Only a few of these researches can be cited here. Demerec has surveyed the X-chromosome of Drosophila for minute deficiencies or cell-lethal mutations produced by X-rays. In 12 out of 13 cases the deficiency of a single locus caused cell death, which supports the view that nearly all the genes take a vital part in the functioning of every cell. In D. virilis, a gene producing intersexes has been found.
