This study finds that high-elevation deer mice have reduced baseline fertility and greater sensitivity to hypoxia compared to low-elevation mice, with gene expression changes suggesting adaptive testicular regression.

This study compares hybrid male sterility in two rodent crosses, finding stage-dependent misexpression and sex-chromosome overexpression, suggesting distinct mechanisms in dwarf hamsters and house mice.

This study identifies widespread recombination suppression on the X chromosome of the dwarf hamster, showing it is independent of structural changes and associated with heterochromatin formation.

The paper develops a program to quantify and categorize nuclear morphology in mouse sperm, finding increased shape variability in lab lines compared to wild-derived lines and subtle cross-direction effects in F1 offspring.

The paper develops an automated method to map FISH signals in sperm nuclei and finds conserved chromosome territory organization across mouse lineages.
