BLACK COCHIN AND WHITE LEGHORN. 



39 



The inheritance of booting is peculiar in that in the first set, Leghorn 

 mother and Brahma father, the booting fails to show that clear dominance 

 which is almost universal ; yet I can hardly suspect the purity of the Dark 

 Brahma male. It would seem that in this series also the mother transmits 

 booting more strongly than the father. 



Series VII. Black Cochin Bantam and White Leghorn Bantam. 

 STATEMENT OF PROBLEM. 



This experiment was undertaken to learn the method of inheritance where 

 one parent is pure white and the other pure black. 



THE RACES AS A WHOLE. 



The Black Cochin Bantam, also called Black Pekin, is a diminutive of the 

 Cochin (fig. 26). It is stated by Wright ("1902, p. 499) that the Pekins 

 came in 1860 from the city of that name. The original color was buff ; the 

 black has probably been engrafted on the race by a cross with some small 

 black race. The Cochins are closely allied to the Brahmas and share with 

 them a chunky form, stout and densely feathered feet and red face and ear- 

 lobes. The White Leghorn has been discussed at page 18. 



TABLE OF CHARACTERISTICS. 



REMARKS ON THE CHARACTERISTICS. 



1. GENERAL PLUMAGE COLOR. In the Black Cochin this is a deep 

 greenish black. No trace of white appears anywhere. 



2. EARLOBE COLOR. In the Black Cochin this is of the dark red or bay 

 characteristic of all the Aseel- Malay group. 



3. VULTURE HOCK. This is well developed in the Black Cochin (see 



page 34). 



MATERIAL. 



The mothers were four Black Cochin Bantams,* very similar, each heavily 

 booted and weighing about 600 grams apiece. Trap nests were not used, 

 but owing to special peculiarities the eggs of the separate mothers were dis- 

 tinguished as A, B, C, and D. 



The father was a White Leghorn Bantam, No. 126, purchased January, 

 1905, from the Cyphers Incubator Company, together with two hens (Nos. 



*Nos. 129, 130, 131, 132, received February, 1905, from Mr. H. B. Kutschbach (fig. 

 26, pi. ix).
