7/ 🔎 More broadly, our results are consistent with a multiple origin of the hexaploid cytotype.
The high genetic diversity of hexaploids and extensive allele sharing between cytotypes could reflect repeated, independent polyploidization events.

6/ 🧬 One population, however, was particularly intriguing.
At Kostalov, some hexaploid individuals showed genetic profiles strongly associated with the diploid cluster. This unusual pattern may represent a rare glimpse of recent or recurrent polyploidization.

2/ 🌱 What happens when plants that look almost identical belong to lineages with different chromosome numbers?
We studied a contact zone in Central Europe where diploid (2×) and hexaploid (6×) Aster amellus populations occur only a few kilometres apart.

5/ 🌍 We also found ecological differences.
Hexaploids occupied a broader climatic space than diploids, with the diploid niche largely nested within the broader hexaploid niche.
This suggests that hexaploids have expanded into a wider range of climatic conditions.

lmao it was the right file, I have been informed that hexaploid kmer spectra are often weird and I should try re-aligning the HiFi reads to the assembly to get a better idea of what's going on 💻🧬🧪
I sent a very polite email asking if maybe I was sent the wrong HiFi data, which I hope to god is what's going on here
hey uhhhh this is supposed to be a hexaploid. is anyone here good at smudgeplot? 💻🧬🧪

based on the documentation I've read so far it seems like a hexaploid should have at least *some* kmer pairs with 6 copies?
