- ERRATA.
- THE PROBLEMS OF HEREDITY AND THEIR SOLUTION[3].
- 1. Shape of ripe seed, whether round; or angular and wrinkled.
- 5. Colour of unripe pod, whether a shade of green; or bright yellow.
- RATIOS
- 1 _ab_ class produce only _ab_’s.
- RATIOS
- The law as Galton gives it is as follows:--
- 1 _AA_ : 2 _AB_ : 1 _BB_.
- We are now presented with some entirely new conceptions:--
- To the new conceptions already enumerated we may therefore add
- Thus we have the conception
- EXPERIMENTS IN PLANT-HYBRIDISATION[23].
- INTRODUCTORY REMARKS.
- SELECTION OF THE EXPERIMENTAL PLANTS.
- The experimental plants must necessarily--
- 1. Possess constant differentiating characters.
- DIVISION AND ARRANGEMENT OF THE EXPERIMENTS.
- THE FORMS OF THE HYBRIDS.[31]
- 2. The yellow colouring of the seed albumen [cotyledons].
- 4. The simply inflated form of the pod.
- 6. The distribution of the flowers along the stem.
- 7. The greater length of stem.
- THE FIRST GENERATION [BRED] FROM THE HYBRIDS.
- THE SECOND GENERATION [BRED] FROM THE HYBRIDS.
- The separate experiments yielded the following results:--
- THE SUBSEQUENT GENERATIONS [BRED] FROM THE HYBRIDS.
- THE REPRODUCTIVE CELLS OF HYBRIDS.
- 1. The egg cells _AB_, _Ab_, _aB_, _ab_ with the pollen cells _AB_.
- 2. The egg cells _AB_, _Ab_, _aB_, _ab_ with the pollen cells _ab_.
- 3. The egg cells _AB_ with the pollen cells _AB_, _Ab_, _aB_, _ab_.
- 4. The egg cells _ab_ with the pollen cells _AB_, _Ab_, _aB_, _ab_.
- There consequently appeared--
- EXPERIMENTS WITH HYBRIDS OF OTHER SPECIES OF PLANTS.
- CONCLUDING REMARKS.
- ON HIERACIUM-HYBRIDS OBTAINED BY ARTIFICIAL FERTILISATION
- A DEFENCE OF MENDEL’S PRINCIPLES OF HEREDITY.
- INTRODUCTORY.
- Such is the judgment a fellow-student passes on this mind
- II. MENDEL AND THE CRITIC’S VERSION OF HIM.
- III. THE FACTS IN REGARD TO DOMINANCE OF CHARACTERS IN PEAS.
- Note then
- V. PROFESSOR WELDON’S QUOTATIONS FROM LAXTON.
- Laxton proceeds:--
- VI. THE ARGUMENT BUILT ON EXCEPTIONS.
- 1 _DD_ : 2 _DR_ : 1 _RR_,
- 1 _DD_ : 1 _DR_
- 1 _DR_ : 1 _RR_.
- 1 _DD_ : 2 _DR_ : 1 _RR_.
- 1 _DD_ : 2 _DR_ : 1 _RR_
- VII. THE QUESTION OF ABSOLUTE PURITY OF GERM-CELLS.
- CONCLUSION.
