Dissimilar Twins 
These seedling pears 
are full sisters, not- 
withstanding their extreme 
dissimilarity of appear- 
ance. They illustrate the 
curious segregation of 
characters —in this case 
the color of the skin—in 
organisms of mized her- 
itage. It is obvious that 
the pear at the right has 
qualities of color that the 
plant developer is sure 
to seize upon.
