Visualization of significant PGLS regression results for a Relationship in rodents between cleaved-Prm2 ω (root-to-tip ω) with sperm head width (relative to total sperm length) and b Relationship in rodents between cleaved-Prm2 ω (root-to-tip ω) with sperm head elongation (sperm head length divided by sperm head width)
