Thus yellow x buff $ notes 22 yellows in a total of 54, and buff ^ x yellow $ 
notes 23 yellows in a total of 57. 
Such as they are these figures indicate that there is no great difference in 
the number of yellow progeny obtained, between using a buff cock and a yellow 
cock. They also show a tendency to partial dominance of yellow, the proportions 
in those noted being 22 : 10 in the first set, and 23 : 18 in the second. The 
" unknowns," however, form too large an element in the offspring to allow of any 
great stress being laid on these results. 
" Buff " recessive. It may be stated definitely that no yellow progeny can be 
obtained from two buff parents. Any reported cases of this sort are probably due 
to one of the parents being really a poor yellow and not a good or " high " buff. 
Some care has to be exercised in distinguishing these birds, but in every case 
the buff tips of the feathers about the head, neck and saddle — the frost or meal — 
can be made out in the buff bird, and is absent in the yellow (Plate III, figs. 
1 and 2).
