Abstract

has been extensively rearranged in large collinear blocks, which until now have been masked by a haploid chromosome number close to the lepidopteran average. We observe that ancient chromosome ends have been maintained and collinear blocks are enriched for functionally related genes suggesting both a mechanism and a possible role for selection in determining the boundaries of these genome-wide rearrangements.

• For another example, there are also some more minor outbreaks of such sudden genomic reorganization in Lepidoptera also. For example, in cabbage white butterflies doi.org/10.1126/scia... : [bsky, 6 points, 0 comments]
