Coat-Colour in Rabbits 



General Scheme of the Experiments. 



My own experiments were started with the idea of investigating 

 more fully the genetics of the Dutch and Himalayan patterns, but they 

 had not proceeded far when it became evident that certain phenomena 

 in connection with the inheritance of colour were unlike any hitherto 

 met with, and promised results of unusual interest. It is with these 

 colour phenomena. that the present paper is concerned. At the same 

 time I can confirm Hurst's statement as to the recessive nature of the 

 Himalayan pattern, though with regard to the nature of the Dutch 

 marking and .its relation to the self-coloured form I am inclined to 

 think that the matter is more complicated than his account appears 

 to imply. Experiments on the inheritance of coat-pattern are still in 

 progress and 1 hope to publish them when more complete. Pattern 

 and colour appear however to be quite independent of one another 

 and in the present paper the results will be treated solely from the 

 standpoint of colour. 



The subjoined scheme provides a general view of the experiments. 



The qualitative result of the various matings is alone indicated. 

 The quantitative results will be found in the various tables to which 

 reference is given.
