This one is another oyster species (Magallana gigas) and Chr 2, 5, 8 and 9 seems different from the others the same way as >5 and <5 in O. edulis.

Thanks for your input, Trevor. What do these kinds of differences mean? No recent genome duplication in this species (Ostrea edulis). The first five chromosomes are metacentric, while the last five are submeta- or subtelocentric. They have more repeats and are preferentially lost in aneuploid cells.

self-promotion, and I'm not it is what you are looking for, but you can have a look at this (the all allelic diversity of a gene is introgressed, locally, into a receiving species, and we provide interpretations): doi.org/10.1534/gene...
