摘要: Breeding programs for endangered species increasingly use molecular genetics to inform their management strategies. Molecular approaches can be useful investigating relatedness, resolving pedigree uncertainties, and estimating genetic diversity in captive wild populations. Genetic data also used evaluate the representation of population genomes within gene-pools. Maintaining a that is genetically representative its counterpart offers means conserving original evolutionary potential species. Okapi, an even-toed ungulate, endemic Democratic Republic Congo, have recently been reclassified as Endangered by IUCN. We carried out assessment ex-situ okapi (Okapia johnstoni) population, alongside investigation into structure populations across geographic range. found while levels nuclear (12 microsatellite loci) variation wild, founder were similar, mitochondrial (833 bp Cyt b, CR, tRNA-Thr tRNA-Pro) was considerably reduced compared with 16 % lower haplotype diversity. Further, both alleles present captivity provided only partial those wild. Thirty haplotypes not captivity, two patterns at loci our samples different samples. Our study highlights importance characterisation populations, even well-managed breeding detailed studbooks. recommend US should further characterised guide translocations between European
