在已知谱系的种群中，对于中等规模的复杂谱系（1,000-2,000个个体和许多近亲繁殖），现在可以计算出每个创始人基因存活数量的精确联合概率分布。我们对亚洲野马（Equus przewalskii）基因存活的分析显示了这种计算的实用性，这是一种现已灭绝的野生野马，在已知的谱系（12代）中有1,516只圈养种群。我们计算了对北美物种生存计划感兴趣的当前种群亚群的遗传多样性，追踪了该物种在圈养历史中遗传多样性的丧失，并确定了北美种群中遗传重要的个体——那些具有独特复制基因的可能性相对较高的个体（在北美任何其他活着的个体中都没有发现的基因）。
In populations with a known pedigree, exact joint probability distributions of numbers of surviving of genes from each founder can now be calculated for moderately large complex pedigrees (1,000-2,000 individuals and much inbreeding). The usefulness of such calculations is shown by our analysis of gene survival in the Asian wild horse (Equus przewalskii), a species now extinct in the wild with a captive population with 1,516 individuals in the known pedigree (12 generations). We calculated the genetic diversity of subsets of the current population interesting to the North American Species Survival Plan, trace the loss of genetic diversity in this species through its history in captivity, and determine genetically important individuals in the North American population-those with relatively high probabilities of having unique copy genes (genes not found in any other living individual in North America).
