Other claims from this paper (11)
- Observation Four additional Oenothera mutants split into parental and Lamarckiana like types each generation.
- Observation Lamarckiana like offspring bred true.
- Observation The dimorphic lines also produced a relatively high proportion of other mutants.
- Observation Parental type specimens averaged about 40 per cent.
- Observation Lamarckiana like plants and mutants comprised about 60 per cent.
- Observation Strong biennials reached 93-97 per cent parental type.
- Observation Dimorphic mutants also occur among allied biennis species.
- Observation Crosses of O. cana followed the pattern of analogous O. scintillans and O. lata crosses.
- Observation Special mutant characters were transmitted through ovules only.
- Observation Investigated pollen did not differ from pure O. Lamarckiana pollen.
- Mechanism The authors infer shared intrinsic causes independent of visible characters.
