Multifurcations

A fact related to the persistence of   ancestral haplotypes in the population is that a single ancestral haplotype will   often give rise to multiple descendant haplotypes,  yielding a haplotype tree with true   multifurcations. Indeed, population genetics theory predicts that the older   the haplotype, the more descendant haplotypes will be associated with it (Box   2).

多分叉

与种群中祖先单倍型的持续性相关的一个事实是，一个单一的祖先单倍型通常会产生多个后代单倍型，从而产生一个具有多岐分叉的单倍型树。事实上，群体遗传学理论预测，单倍型越老，其后代的单倍型越多（框注2）。
