[The 3'-UTR polymorphism of dopamine transporter gene in hadza and datoga males].

The study of VNTR-polymorphism and the molecular struc ture of 3'-UTR of the dopamine transporter gene (DAT1/SLC6A3) was performed in hadza and datoga males. It was shown that hadza and datoga differed in allele and genotype frequencies. Allele with 9 repeats in 3'-UTR is more common in hadza as well as homozygous genotype DAT19/9.

[Polymorphism of 5-HTTLPR and Stin2 loci of the serotonin transporter gene in males of African ethnic populations Hadza and Datoga].

A molecular-genetic study of 5-HTTLPR and the Stin2 loci of the serotonin transporter gene (5-HTTL) in males of the African ethnic populations Hadza and Datoga, which differ in the level of culturally acceptable aggression, was carried out. The distribution of allele and genotype frequencies of these two loci was established. It was shown that the frequency distribution of genotypes and alleles among Hadza and Datoga in the examined samples is practically identical by the VNTR-polymorphism of both loci.

[Redirection and consolation in hamadryas baboons].

Post-conflict interactions between victims and non-involved group members was investigated in the troop of hamadryas baboons, Papio hamadryas. Observations were done in the Russian Primate Center, Adler in 1996-1997. Redirected aggression, initiation of affiliation from the side of victims towards third parties and consolation were registered during this study.

[Mechanisms of reproductive behavior in humans: olfactory markers of males' attractiveness].

The present work represents a pilot study in the area of olfactory communication in humans. On the basis of experiments, it is demonstrated that women are able to detect, by means of smell, a number of morphological and psychological characteristics of men. The samples of sweat from 29 young men were collected, as well as anthropometry measurements (interpupillary distance, height and width of the lower jaw, and so forth) and behavioral characteristics (personality questionnaire NEO, risk-taking questionnaire, Sandra Bem masculinity and femininity indices, a self-rating on aggression Buss-Perry questionnaire).

[Reconciliation in hamadryas baboons, Papio hamadryas: testing the relationships quality hypothesis].

Post-conflict interactions between former opponents were investigated in a troop of hamadryas baboons, Papio hamadryas. This species is known for it's multilevel structure with evidently expressed hierarchy between males and females. Due to this fact hamadryas baboons represent an ideal object for testing the "relationship quality" hypothesis.
