Abstract

Less than 10% of all mammal species have a monogamous social structure. One of the species that exhibit this type of behavior is Microtus ochrogaster, prarie vole, which has been used in the last decade as a model organism for neuroendocrine research on reproductive behavior. Research has shown that monogamous voles have increased concentration of vasopressin receptors in nucleus accumbens and ventral pallidum areas of the brain. Gene for vasopressin 1a receptor shows polymorphism of repetitive microsatellite sequence in the regulatory promotor region among vole species. Monogamous voles have an expansion of repetitive microsatellite DNA whereas promiscuous speceis do not. Although there is no sequence in the human AVPR1A homologous to the one found in monogamous voles, humans do have polymorphic sequences in this region associated with partner bonding, martial problems and marital status in general
