The deep conservation of the Lepidoptera Z chromosome suggests a non-canonical origin of the W

The canonical scenario of sex chromosome evolution is through the differentiation of ancestral pairs of autosomes. Here, Fraïsse and colleagues use a comparative genomic analysis that shows the deep conservation of the Z chromosome in Lepidoptera and supports a non-canonical origin of the W chromoso...
