albmo mice contain some colour in a latent condition; those 
with which he worked were represented by the following 
formulae ” of heredity ” 
Homozygotes AG; AN; AJ. 
Heteorozygotes AG AN ; AG AJ : AN AJ. 
In the visible expression of the colours (when C is present) 
yellow is dominant over grey and over black, and grey is 
dominant over black. This being the case, Cuenot finds that 
e s w is rigidly followed in the formation of the 
gametes. 
Cninot gives the following example, being one of time 
possible methods by which all three colours yellow, gray,and
