Amino acid substitutions of PRM1 and TNP1 in mammals lacking intact PRM2 or TNP2. a) Specific amino acid substitutions observed in TNP1 and PRM1 across mammalian branches. b) Changes in the physicochemical properties (charge, volume, and hydrophilicity) of specific amino acid substitutions, analyzed using HOPE (https://www3.cmbi.umcn.nl/hope/).
