In so doing I shall be able, perhaps, to make 

 a somewhat clearer exposition than has hitherto 

 been attempted of certain aspects of heredity 

 that are peculiarly important from the stand- 

 point of the practical plant developer. 



UPPER CASE QUALITIES 



We have learned something in earlier chapters 

 about unit characters and the way in which they 

 are blended or mosaiced together to make up the 

 personality of any individual plant. 



It will be recalled that where the two parents 

 of a given individual have opposing qualities as 

 regards a given characteristic where one, let us 

 say, is black and the other white it is quite the 

 rule for one quality to dominate the other in such 

 a way that the offspring precisely resembles, as 

 regards that quality, the dominant parent in 

 this case the black one and resembles the other 

 parent seemingly not at all. And we have 

 learned also that the latent or recessive character 

 that is thus subordinated in this case whiteness 

 will reappear in a certain proportion of the 

 offspring of the succeeding generation. 



Now, it has been found convenient by recent 

 experimenters to adopt a graphic method that 

 will make the printed accounts of their experi- 

 ments more readily comprehensible. The ex-
