The width of an average pod from each of the different plants 
showed the following range :— 
Width .. 19mm.. . 18 . . 17 .. 16 .. 15 .. 14 .. 13 .. 12 
Number of plants 1 .. 6.. 5 . . 8.. 4.. 5.. 2.. 1 
We may regard this as indicating the proportion 7 wide : 17medium : 
8 narrow, or nearly 1:2:1. The Mendelian ratio thus makes its 
appearance in spite of much variability. 
The 11 plants which arose from green seeds (F 2 ) gave rise to 
exclusively green seeds (F 3 ), namely to 88 such seeds.
