This study reports the lowest germline mutation rate in mammals and a typical male mutation bias in the gray short-tailed opossum, suggesting alternative mechanisms to cell division drive sex-specific mutation rates.

The paper characterizes the genetic architecture of eight laboratory strains of the opossum using ddRAD-seq and whole-genome resequencing, identifying SNPs and confirming inbred strains.

The paper identifies and characterizes GSTA3 mRNA and protein sequences in dog, goat, and opossum, showing high conservation with human and horse GSTA3 and suggesting differences in enzymatic activity.

The paper shows non-linear sequence similarity between Xist and Rsx repeat domains, suggesting shared functional roles through similar protein-binding motif enrichments.
