Abstract. Drosophila ventral appendages are considered to be serially homologous structures derived from a ventral appendage ‘ground state’ and shaped by d

Abstract. Within the arachnids, chromosome-level genome assemblies have greatly accelerated the understanding of gene family evolution and developmental ge

Whole genome duplication (WGD) generates new genetic material that can contribute to the evolution of the regulation of developmental processes and phenotypic diversification. A WGD occurred in an anc...
