  "summary": "Newly formed polyploids often suffer extensive aneuploidy and chromosome rearrangement. We explored whether these are predictable and conserved across genotypes. We quantified whole-chromosome and segmental aneuploidy in progeny arrays of neo-polyploid Arabidopsis thaliana from two accessions (Col-0 and Ler). 29% of progeny had whole-chromosome and/or segmental aneuploidies. Strikingly, segmental…",
