3. THE GENETICS OF THE SILKWORM 



1964

 Price: 50 s. 



Much genetical work has been done on the silkworm, Bombyx mod (parti- 

 cularly, but not exclusively in Japan). So far, however, no general account of 

 this work has been available in English. The present book provides a synthesis 

 of those topics on which most of this work has concentrated. It is a book written 

 primarily for the specialist in insect physiology and genetics. The reason why 

 it is reviewed here is that it contains much material of interest to insect develop- 

 mental physiologists. In the author's opinion the silk worm is an ideal organism 

 for the study of physiological and developmental problems. 



The following sections of the book may be specifically mentioned: a chapter 

 on the biology of the silkworm (life cycle, embryology, formation of gonads, 

 spermatogenesis, oogenesis); a chapter on the E-group of mutant alleles, which 

 have interesting pleiotropic effects on early stages of embryonic development, 

 particularly on segmental differentiation; a chapter on sex determination; a 

 chapter on genetic control of hormonal mechanisms; chapters on mosaicism and 

 on parthenogenesis and polyploidy. Other chapters discuss more specifically 

 genetical and physiological topics. 



The book contains an extensive bibliography, in which Japanese titles of 

 course predominate. However, many papers in other languages are also cited. 

 The book is adequately illustrated and contains a list of silkworm genes, and 

 subject and author indexes.
