Résumé :	DNA fingerprinting was used to estimate relatedness and genetic diversity within the captive Siberian Crane population consisting of 21 founders, 18 of which originated from the Yakut flock, and 3 originating from the Ob River delta population. Relationships among captive individuals, estimated by band-sharing analysis and the hierarchical clustering technique, demonstrated the heterogeneous structure of the Siberian Crane population, harbouring both close relatives and non-relatives. The 18 captive founders from the eastern Siberian population were differentiated into two separate groups of individuals some of which shared the same genetic markers. Quantitative characteristics of the Yakut captive population group, such as average percentage differences (APD=77.9) and a heterozygosity of 0.85, suggest a high level of genetic variability in the wild population of eastern Siberia. Thus, genetic fingerprinting facilitates the study of genetic differentiation, kinship, and management of the Siberian Crane gene pool both in captive and in threatened, wild populations.
