(4) Offspring of the form with simple coloured seeds (f.) :— 
(r) 1 constant in F 3 (f.). 
(s) 2 giving (f.) and (w.). 
(5) Offspring of forms with a white testa (w.) :— 
(t) 16 constant in F 3 (w.). 
Thus 64 individuals of F 2 should include 19 forms of constitution. 
Out of the 25 plants obtained in F 2 , 10 were found on examination of 
their offspring to have been of the following forms :—1 ( b ), 1 (e), 4 (/), 
1 (g), 3 (h), 1 (l), 1 (n), 1 (p), 1 (q), 1 (r), 1 (s), and 3 ( t), as may be seen 
on consulting the table. The remaining plants did not yield a 
sufficient number of offspring to allow of their character being 
determined. No unexpected type appeared among the whole series 
of 467 plants grown in F 3 , and the proportions in which the visible 
types appeared were also in reasonable agreement with expectation. 
Thus the total offspring of the 3 plants of type ( h) was as 
follows :— 
Total. (m.p.f.) (m.f.) (p.f.) (f.) (w.) 
169 .. 82 .. 20 .. 21 .. 9 .. 37 
Expectation .. 192 .. 81 .. 27 ... 27 .. 9 .. 48 
And the offspring of the 4 plants of type (/) were as follows :— 
Total. (m.p.f.) (rn.f.) (w.) 
147 . . 75 .. 24 .. 48 
144 .. 81 .. 27 .... 36
