Other claims from this paper (5)
- Mechanism A shift early in development in the ovule-to-ovary size allometry governs the transition from single- to multi-ovulate state in Phlox.
- Association A larger ovary yields a larger, single seed in the other developmental trajectory.
- Observation Most measured traits in the Phlox drummondii x P. roemeriana F2 population show unimodal distributions, consistent with multiple loci.
- Association Ovary size, ovule number, flower size and flower number are significantly correlated among F2 plants.
- Observation Environmental variation alone cannot explain phenotypic differences in Phlox longifolia across 102 populations.
