Step-by-step evolution of neo-sex chromosomes in geographical populations of wild silkmoths, Samia cynthia ssp
Original language description
Geographical subspecies of Samia cynthia (Lepidoptera: Saturniidae) differ considerably in sex chromosome constitution owing to sex chromosome fusions with autosomes (the so-called neo-chromosomes), which leads to variation in chromosome numbers. We cloned S. cynthia orthologues of 16 Bombyx mori genes, mapped them to chromosome spreads of S. cynthia subspecies by fluorescence in situ hybridization (FISH) to determine the origin of different parts of S. cynthia neo-sex chromosomes. Our results clearly showed a step-by-step evolution of the neo-sex chromosomes by repeated autosome-sex chromosome fusions. We suggest that the rearrangements of sex chromosomes may facilitate divergence of S. cynthia subspecies towards speciation.
