5. Style short, with large pollen-grains — the thrum-type — . 

 and Stj'le long-, with small pollen grains — the pin-type — 

 (Bateson and Gregory (8)). 



De V r i e s found in Oenothera that his mutational form 

 hrevisiylis was recessive to the normal, or long-styled type (115). 



6. Beardless and bearded ears. Wheat and Barley (Biff en (12). 

 Tschermak (94), Spillman (89)). 



7. Pointed and blunt pods. Pisum (Tschermak (96), R. E. C. (10a)). 



8. Round seed and wrinkled seed P«5mw. (Mendel, and many 

 others.) The round seeds have large starch grains, those of 

 the wrinkled being small (Gregory (57)) or compound. 



9. Starchy endosperm giving a full seed and sugary endosperm 

 giving a shrivelled or wrinkled seed. Zca Mays (de Vries 

 (109). Correns (26), Lock (70)). (See Fig. 5.)

 the mixture of the two kinds of seed in the F., generation. (From a specimen raised 



by E. H. Lock.) 



10. Normal habit and Waltzing habit. Mouse (v on G u a i t a (57 a), 

 Darbishire^) (44, 45)). 



11. Various types of comb (e.g., rose-comb and pea-comb) and the 

 single comb. Fowls (R.E.C. (10a, b), Hurst (64)).

 Wheat \Wiii%\i (12)). 



16. Normal hair and long or Angora hair Bahhit (Hurst (65), 

 Castle (16)). 



1) The fact that in F, the number of Waltzing mice (97 : 458) falls below 

 expectation is no doubt due to their relative delicacy.
