Constraints on chromosome evolution revealed by the 229 chromosome pairs of the Atlas blue butterflyThe genome of the Atlas blue butterfly contains ten times more chromosomes than most butterflies, and more than any other known diploid animal. Wright et al. show that this extraordinary karyotype is ...tinyurl.com
