EAST, EDWARD MURRAY, and JONES, DONALD FORSHA. Inbreeding and outbreeding: their genetic and sociological significance. (Monographs on experimental biology) il *$2.50 Lippincott 575

20–352

“Whether close inbreeding causes deterioration of the race and cross-breeding re-invigorates it, is a question that has long been disputed. It was not until the development of the Mendelian theory that a sufficiently powerful method of analyzing the problem was discovered. The book by Professor East and Dr Jones gives an account of the solution of the problem by means of this theory. The data which East and Jones have here brought together have a wide applicability to practical animal and plant breeding. The authors also attempt to apply them to the field of human heredity.”—J Philos
