Behavioral Genetics Potluck

THIS article deals with the idea that differences in levels of polymorphism of serotonin transporter and monoamine oxidase A genes can influence social structures between macaque species in a region.  Species of macaque with low agression and relaxed dominance structure (dominance structure is agression based) are functionally monomorphic at these loci.  More agressive and intolerant macaque species with strict hierarchy are polymorphic at these loci.
