ON HEREDITY IN KABBITS. 291 



Angoras in each case produced a mixture of shorts and Angoras 

 in Mendelian proportions. 10 extracted hybrids mated together 

 and with 2 hybrids of the first generation produced 41 young, of 

 which 31 had short coats and 10 were Angoras ; the Mendelian 

 expectation for 40 young is 30 shorts and 10 Angoras. The 

 matings were as follows : —

7 extracted hybrids mated with 8 Angoras produced 50 young, 

 of which 27 had short coats and 23 were Angoras ; the Men- 

 delian expectation is 25 shorts and 25 Angoras. The matings 

 were as follows : —
