THE CARRIERS OF THE HERITAGE 35 



14. CONCLUSION 



The supposition that the chromosomes, with cer- 

 tain chemical reservations, are the morphological 

 carriers of the heritage forms an excellent working 

 hypothesis, and this chapter may suitably be closed 

 with a second quotation from Professor Wilson. 

 " In my view studies in this field are at the present 

 time most likely to be advanced by adopting the 

 comparatively simple hypothesis that the nuclear 

 substances are actual factors of reaction by virtue 

 of their specific chemical properties; and I think 

 that it has already helped us to gain a clearer view 

 of some of the most puzzling problems of genetics."
