ties; and that in the second generation, with rare 

 exceptions, there is a segregation and recombina- 

 tion of the racial qualities of the original parent 

 species, in which the extreme forms may more 

 or less closely duplicate one parent or the other, 

 and the intermediate forms may show almost 

 every conceivable gradation between the two. 



They have demonstrated, further, that it is 

 possible, by selecting among the second-genera- 

 tion hybrids the individuals that exhibit any de- 

 sired combination of qualities, to develop, in the 

 course of a few generations of inbreeding, races 

 in which this combination of qualities is so accen- 

 tuated and fixed as to constitute a distinguish- 

 ing characteristic of a new variety quite unlike 

 the original forms. 



Moreover, that the later-generation hybrids 

 might reveal racial traits that were not observ- 

 able in either of the parent species. 



The segregation and redistribution of char- 

 acters often gave opportunity for the appearance 

 of qualities that have long been submerged^ 

 which by cumulative selection produced new 

 characters and qualities never before in existence. 



As a tangible illustration, hybrids in the first 

 generation may show an enhanced capacity for 

 growth, and the later generation hybrids may be 

 graded from groups of dwarfs at one end of the
