De novo chromosome-length assembly of the mule deer ( Odocoileus hemionus ) genome

The mule deer ( ) is an ungulate species that is distributed in a range from western Canada to central Mexico. Mule deer are an essential source of food for many predators, are relatively abundant, and commonly make broad migration movements. A clearer understanding of the mule deer genome can improve our knowledge of its population genetics, movements, and demographic history, aiding in conservation efforts. Their large population size, continuous distribution, and diversity of habitat make mule deer excellent candidates for population genomics studies; however, few genomic resources are currently available for this species. Here, we sequence and assemble the mule deer genome into a highly contiguous chromosome-length assembly for use in future research using long-read sequencing and Hi-C technologies. We also provide a genome annotation and compare demographic histories of the mule deer and white-tailed deer using the pairwise sequentially Markovian coalescent model. We expect this assembly to be a valuable resource in the continued study and conservation of mule deer.
