INHERITANCE IN POULTRY. 



WHISKERS OR MUFF. 



This is certainly a new character and a positive variant. The distribution 

 of its occurrence in crossing is as follows : 



Muffling is apparently dominant. 



BEARD. 



This is also a new, positive, variant. The distribution of its occurrence 

 is as follows : 



Beard is apparently dominant, but often imperfectlj' so. 



FEATHER FORM. 



Si/ki>iess is a new characteristic and, approximating as it does the juvenile 

 down condition, a negative one. When a Silky is crossed with a Jungle fowl 

 the offspring are plain. Silkiness is recessive to uon-silkiness — the retrograde 

 to the progressive type. 



Friz~ling is likewise a new characteristic — a positive character added to 

 the perfect feather. The distribution of the occurrence of silkiness and friz- 

 zling is as follows : 



The Frizzle fowl used were doubtless heterozygous. When non-frizzled 

 birds are crossed i?iter sc they produce only plain offspring. Frizzling is 

 dominant over noa-frizzling — the progressive over the primitive.
