The Making of Species 



the father in being rough-coated, but after the 

 mother in being pigmented and short - haired. 

 This form of inheritance is usually seen only in 

 crosses between two types which differ in but 

 few of their characters. 



III. The offspring may display a blend of the 

 characters of the two parents. They may be 

 intermediate in type. They are not of necessity 

 midway between the two parents ; one of the 

 parents may be prepotent. The crosses between 

 the horse and the ass show this well. Both the 

 mule, where the ass is the sire, and the hinny, 

 where the horse is the sire, are more like the ass 

 than like the horse ; but the hinny is less ass- 

 like than the mule. The offspring between a 

 European and a native of India furnishes a 

 good case of blended inheritance ; Eurasians are 

 neither so dark as the Asiatic nor so fair as the 

 European. 



IV. The offspring may show a peculiarity of 

 one parent in some parts of the body and the 

 peculiarity of the other parent in other parts of 

 the body. This is known as particulate inherit- 

 ance. The piebald foal, which is the result of a 

 cross between a black sire and a white mare, is a 

 good example of such inheritance. This does 

 not appear to be a common form of inheritance. 



V. The usual kind of inheritance is perhaps 

 a combination between the forms II. and III.
