Five new mutations in the Syrian hamster: furloss, fur-deficiency, juvenile gray, ashen, and quaking.

Five new mutations in the Syrian hamster are described: furloss, a simple recessive trait affecting the quality of hair; fur-deficiency, a simple recessive trait affecting the quantity of hair and longevity; juvenile gray, a simple recessive trait affecting coat color and body size; ashen, a semidominant trait affecting both coat color and quantity of hair; and quaking, a simple recessive trait affecting motor activity. Gene symbols, fs, Rfd, jg, A, and q are proposed for these mutations.
