Abstract
AN account was recently given of some new mutations in Gammarus chevreuxi Sexton (NATURE, Feb. 6, 1926). A certain white-body mutation did not behave in a simple Mendelian manner. In this mutant the body is devoid of the normal green and brown pigments. The mutant is recessive to the normal ‘black-eyed’ form, and the homozygote mutant has black eyes and white body (white-body Black). With certain exceptions to be considered later, ‘Whitebody’ is recessive to another mutant, the ‘New Red’ (with red eyes and normally pigmented body). But if homozygous for ‘White-body’, the ‘Red’ fails not only to develop body-colour but also the red eye colour; a ‘White’ individual in both eyes and body results.
