THE SUNBERRY 309 



The hybrids of the first generation often resem- 

 ble one parent more than the other. The hybrids 

 of the second generation show wide variation, 

 some of them reverting to one ancestral strain 

 and some to the other, the characteristics of each 

 being variously segregated and recombined. 



Nothing like the direct and complete repro- 

 duction of the characteristics of the hybrid in its 

 offspring, as shown by the Sunberry, is mani- 

 fested in the case of these familiar hybrid forms 

 that spring from the union of closely related 

 species or varieties. 



WHAT THE SUNBERRY TEACHES 



All this should be borne in mind by anyone 

 who is prone to reduce the principles of heredity 

 to formulas of undue simplicity. 



The new formulae of the Mendelians, for ex 

 ample, which have such admirable application to 

 many cases of the crossing of related forms 

 where particular unit characters are segregated 

 and recombined have no application, or to be 

 applied must be greatly distorted from their 

 original implications, in dealing with such a case 

 as that of the Sunberry. 



Here there is no clear balancing of dominant 

 and recessive factors, with the overwhelming 

 presentation of the dominant factor in the first
