Gene extinction probabilities over the ancestral genealogy of Tristan da Cunha are analysed, to determine the probability distributions of numbers of surviving distinct founder genes. Autosomal, X-linked and Y-linked genes are considered, and also the bivariate distributions of genes originating in males and in females. One founder group shows a greater variety of surviving genes than another, although there is little difference in their total genetic contributions. This excess variety is concentrated in male lines of descent. The paper demonstrates the types of analysis that can be used to illuminate and summarize lists of gene extinction probabilities.
分析了特里斯坦 - 达库尼亚群岛祖先谱系上的基因灭绝概率,以确定存活的不同奠基者基因数量的概率分布。考虑了常染色体、X连锁和Y连锁基因,以及起源于男性和女性的基因的双变量分布。一个奠基者群体比另一个群体显示出更多种类的存活基因,尽管它们的总遗传贡献差异不大。这种多余的多样性集中在父系血统中。本文展示了可用于阐明和总结基因灭绝概率列表的分析类型。
