Hormones and Heredity Most of the characters in domesticated varieties are obviously gametogenic mutations, but the lop-ear in rabbits may be, partly at least, somatogenic.

Hormones and Heredity It has been the main argument of this volume that there are two distinct kinds of characters in all organisms—namely, those of somatogenic origin and those of gametogenic origin. Hormones and Heredity Such disturbances he says, acting on the germ-cells, would be truly somatogenic.
