36 INHERITANCE IN POULTRY. 



from the foot than in the Minorca. Plain feathered heel is dominant, but 

 not perfectly so. 



CONCLUSIONS. 

 This series of experiments is only begun. Conclusions as to dominance 

 are tentative until tested in the second hybrid generation. The Minorca 

 characteristics appear to dominate in (i) general black color, (4) white ear- 

 lobes, (6) black foot and beak, and (8) absence of vulture hock. Dark 

 Brahma characteristics appear to dominate in (2) wing bar, (3) pea comb, 

 (5) yellow iris, and (7) foot feathering. In every case, however, dominance 

 is imperfect. In .some cases, at any rate, (5, 7), it is the new, additional, 

 or positive characteristic that dominates. 



Series VI.— White Leghorn and Dark Brahma, 

 STATEMENT OF PROBLEM. 



THE RACES AS A WHOLE. 



It is proposed to investigate the behavior of characteristics when the heavy- 

 bodied, short and stout legged, loose-feathered, dark-colored Asiatic type is 

 crossed with the slender, tall-legged, close- feathered, white Mediterranean 

 type. Both types are ancient, but the Brahma must be regarded as nearer 

 its ancestral form, Aseel-Malay-Indian, than the L,eghorn is to the Jungle 

 fowl.

REMARKS ON THE CHARACTERISTICS. 



I. Hackle Color. — Among most poultry that are of broken color the 

 hackle feathers are unlike those of the rest of the plumage. They have a 

 dark center and a lighter lacing. In the Malays and Indians the}' have a 

 red center edged with green. In the Gallus bayikiva female the hackles have 

 a black center (with straw-colored shafting) and straw-colored lacing. This 

 is the type of hackle feather found in the male Dark Brahma. It is found,
