It is evident from what has just been stated that we may also use the term hybrid in reference to heterozygous individuals belonging to the same species. An animal may be a hybrid for certain characteristics and yet be pure-blooded so far as the species or variety is concerned, the characteristics which it possesses being recognized as varying within the species. 600. Distribution of Characteristics in Hybrids.—In crossing two individuals homozygous for the same pair of characters it is evident that.
