(c) wr. y. seeds—7 plants : 2 with 57 wr. y. seeds only, 
and 5 with 56 wr. y. : 28 wr. g. 
(d) wr. g. seeds—3 plants : 2 with 35 wr. g. only, and 1 
with 19 sm. g. only. (c. p. below.) 
623.4.3. (a) sm. y. seeds gave rise to 14 plants :— 
(al) 7 plants with 133 sm. y., 50 sm. g., 48 wr. y., and 22 
wr. g. 
(a2) 3 plants with sm. y. and sm. g. seeds : 52 : 25. 
(a3) 4 plants with sm. y. and wr. y. seeds : 85 : 34. 
(b) sm. g. seeds—8 plants : 3 with 105 sm. g. seeds 
only, and 5 with 102 sm. g. : 42 wr. g. 
(c) wr. y. seeds—10 plants : 1 with 26 wr. y. only, 
and 9 with 178 wr. y., 53 wr. g. 
(d) wr. g. seeds—3 plants with 100 wr. g. seeds only. 
623.5.5. (a) sm. y. seeds gave rise to 43 plants :—16 with 323 
sm. y. seeds only, and 27 with 427 sm. y. : 140 wr. y. 
(b) wr. y. seeds—30 plants with 811 wr. y. seeds only. 
623.5.9. wr. g. seeds only gave rise to 20 plants with 248 wr. g. seeds. 
The unexpected occurred in a single case only, in which a supposed 
wr. g. seed of No. 623.4.1 turned out to have been really sm. g., there 
being thus 1 error among 249 cases of F 3 plants, all the rest of which 
follow exactly the Mendelian expectation. 
4.— Telephone crossed with Ringleader. 
A.— The Parent Types have already been described. 
B.— The Cross-bred Forms. 
Stated in brief the result of the present crosses was to confirm 
exactly Mendel’s description of the effect of crossing a wrinkled green 
pea with a smooth yellow one. 
1. Telephone x Ringleader. —15 pollinations resulted in the pro¬ 
duction of 12 pods containing 42 seeds, all smooth and yellow, though 
resembling in general shape the smooth seeds of Telegraph, or those 
of Telephone “ filled out ” so as to do away with the wrinkles. 
2. Ringleader x Telephone. —4 pollinations : 2 pods with 2 seeds 
in each. These exactly resembled the normal seeds of the plants 
which bore th,em.
