Other claims from this paper (5)
- Observation Normal pollen had little competitive advantage over 3D-deficient pollen in selfed substitution monosomics.
- Observation Initial pollen tube growth was faster in 21-chromosome than 20-chromosome pollen.
- Observation Ultimately both pollen types functioned in the proportions in which they formed.
- Observation The 21-chromosome pollen lacked that advantage with three other 3D monosomic varieties.
- Observation Normal pollen had a competitive advantage in all reciprocal crosses, affecting up to about 90% of fertilizations.
