Abstract

Factors affecting the probabilities of gene loss are discussed, with particular attention given to population expansion, sex ratio and inbreeding. Much of the variation in gene survival probabilities among breeds can be explained by differences in expansion rate, sex ratio and family size, with little or no influence of average inbreeding and population size.

摘要

影响基因丢失概率的因素进行了讨论，特别关注了种群扩张、性别比例和近亲繁殖。在不同品种中，基因存活概率的变化很大程度上可以用扩张率、性别比例和家庭规模的差异来解释，而平均近交率和种群规模的影响很小或可以忽略不计。
