Other claims from this paper (4)
- Observation Cuphea species had haploid chromosome numbers from 6 to 22.
- Observation C. leptopoda accession 264 had n = 8 whereas the other three accessions had n = 10.
- Observation Calculated chiasma formation probabilities ranged from 0.565 to 0.905 across accessions.
- Method / resource Meiotic pairing in a diploid interspecific Cuphea hybrid established a genomic affinity estimation protocol.
