Evaluating restriction enzyme selection for reduced representation sequencing in conservation genomics. [PDF]

open access: yesMol Ecol Resour
Abstract Conservation genomic studies in non‐model organisms generally rely on reduced representation sequencing techniques based on restriction enzymes to identify population structure as well as candidate loci for local adaptation. While the expectation is that the reduced representation of the genome is randomly distributed, the proportion of the ...
