Other claims from this paper (4)
- Observation Population structure and phylogenomic analyses indicate that northwestern Yucatán harbors greater genetic diversity than smaller, dispersed populations in northeastern Yucatán and the Caribbean basin.
- Observation Genetic load and transposable element burden are lowest in northwestern Yucatán relative to other regions.
- Observation Populations from Florida and elsewhere in the Caribbean basin maintain unique pockets of diversity.
- Mechanism Selection analyses suggest cotton domestication involved long-term accumulation of mutations with relatively minor phenotypic effects rather than a punctuated process involving major domestication genes.
