Abstract
The theory of homogamy suggests that individuals prefer partners with self-similar traits. From an evolutionary perspective, small genetic differences between parents translate into a higher parental-offspring relatedness, and can thus be based on extended kin selection.
Although previous research has provided evidence for homogamous mate preferences and mate choice in majority of traits, dyadic hierarchy seems to follow rather the principle of complementarity in heterosexual couples. The main aim of this study was to test whether similarity/complementarity in relationship dominance among long-term heterosexual and homosexual couples predicts higher relationship satisfaction.
