Abstract excerpt
The early evolution of sex chromosomes has remained obscure for more than a century. The Vandiemenella viatica species group of morabine grasshoppers is highly suited for studying the early stages of sex chromosome divergence and degeneration of the Y chromosome. This stems from the fact that neo-XY sex chromosomes have independently evolved multiple times by X-autosome fusions with different autosomes. Here, we...
