It will be seen that the homozygous groups in F, are quite distinct in 
shape ; thus, whilst there is some overlapping in length, the groups are quite 
separate as regards breadth and length ~ breadth. They do not reproduce 
very exactly the measurements of the two parents. By an oversight only 
the actual parent plants of the cross were measured. Had the average of a 
number of plants of each parental type been taken, it is possible that a closer 
approximation would have resulted. This point will probably be settled in 
future generations. 
In Plate III, figs. 1-6, photographs are given of single grains from the 
two parents, F, and the three groups of F, of the above cross. The grains 
were selected so that each corresponds in its measurements with the average 
of the group from which it was taken,
