produced plants partly tall and partly dwarf. 

 As in the second generation so in this the 

 third these dwarf individuals could be 

 depended on to breed true to type, a condition 

 of things that was continued throughout an 

 indefinite number of subsequent generations. 

 But the tall peas of the third generation did 

 not all transmit their character throughout 

 the following generations, only some possess- 

 ing this power. The results can be best set 

 forth in such a diagram as is here inserted.

This work of Mendel's has been fully 

 confirmed by other investigators, so that it 

 may be confidently predicted that tall and 

 dwarf peas, if bred together in sufficient 

 numbers, will produce similar results in the 

 generations that follow. 



Of late years Mendel's law has been applied
