Homogamy, genetic similarity, and imprinting; parental influence on mate choice preferences T. Bereczkei*, P. Gyuris, P. Koves, L. Bernath Department of General Psychology, University of Pecs, Ifjusag 6, 7624 Pecs, Hungary Received 30 March 2001; received in revised form 5 September 2001 Abstract Whereas the hypothesis of genetically mediated homogamy has been supported by several studies, cer- tain theoretical and methodological criticisms have been raised against genetic similarity theory. As an alternative approach to assortative mating, we suppose that imprinting-like mechanisms, rather than ‘‘direct’’ genetic detection, are responsible for choosing similar spouses. In a study aimed at comparing more than 300 facial photographs of family members and controls, the judges correctly matched wives to their mother-in-law at a significantly higher rate than expected by chance. Furthermore, a higher degree of similarity was ascribed between the husbands’ mother and the husbands’ wife than between the husbands and their wives. A regression analysis has revealed that men who had been more frequently rejected by their mother during childhood were less likely to choose mates who resemble their mothers in physical appearance. These results suggest that under the influence of childhood experiences, sons internalize their mother’s phenotype as a template for acquiring similar mates. # 2002 Published by Elsevier Science Ltd.

Introduction The studies of so-called assortative mating or homogamy have shown that the majority of mates resemble each other in a high number of traits. Positive correlations have been found between their race, socioeconomic status, age, intellectual ability, education, personality vari- ables, physical attractiveness, vocational interest and anthropometric measures (Ahern, Cole, Johnson, & Vandenberg, 1985; Bereczkei & Csanaky, 1996; Bereczkei, Vo¨ro¨s, Ga´l, & Berna´th, 0191-8869/02/$ - see front matter # 2002 Published by Elsevier Science Ltd.
