In the absence of pedigree information, the determination of genetic distinctness of populations can only be made by genetic methods. Using DNA fingerprinting on the North American captive herd of Speke's gazelle Gazella spekei, we were able to address two hypotheses. First, two new individuals were found to have come from a genetically distinct population (P = 0.008, permutation test), and represent potential new founders to be added to the population. Secondly, genetic similarity was not significantly correlated with relatedness under extreme inbreeding and very close relationship (coefficient of relationship range 0.304-0.717).
在没有谱系信息的情况下,只能通过遗传方法来确定种群的遗传独特性。通过对北美圈养的斯氏瞪羚(Gazella spekei)种群进行DNA指纹分析,我们能够验证两个假设。首先,发现两个新个体来自一个遗传上不同的种群(P = 0.008,置换检验),它们代表了可能加入该种群的潜在新奠基者。其次,在极端近亲繁殖和非常近的亲缘关系(亲缘系数范围为0.304 - 0.717)下,遗传相似性与亲缘关系之间没有显著相关性。
