INHERITANCE OP BLUE COLOR, SPANGLING, AND BARRING. 



83 



On the assumption that the zygotic formula of both hens and cocks is 

 BbNJVw (compatible with a barred plumage) we get four-sixteenths of the 

 offspring white, three-sixteenths mottled or barred and nine-sixteenths 

 black or Game, thus approximating the observed result; i.e., 21, 16, 47 as 

 compared with 23, 21, 40. The result supports the hypothesis of a barring 

 factor, B.
