Full text of MNL contribution: Research News: 1. Greasy, Gs. First noted in later descendent of irradiated male, but probably of spontaneous origin. Very closely linked to, or allelic with, Ta. Gs/+ females superficially resemble Ta/+ females. Gs/Y males and Gs/Gs females have uniformly shiny fur. They lack the following features of Ta/Y: sticky tail, bare patches behind ears, decrease in yellow pigment along mid-dorsal. More detailed analysis of hair is in progress. (Larsen)
