 law propounded by Mendel with regard to the inheritance of characters, and 

 explains the occurrence of dominant and recessive characters in hybrids with 

 special reference to our domestic animals. 



The dravidng- up and printing' of pedigrees, Wilsdorf {Ztschr. Gestiitk., 8 

 {1913), No. 3, pp. 63-67; abs. in Internat. Inst. Agr. [Rome], Mo. Bui. Agr.
