Abstract

Sexual processes alter associations among alleles. To understand the evolution of sex, we need to know both the short-term and long-term consequences of changing these genetic associations. Ultimately, we need to identify which evolutionary forces--for example, selection, genetic drift, migration--are responsible for building the associations affected by sex.

摘要

有性生殖过程会改变等位基因之间的组合。为了理解有性生殖的进化，我们需要了解改变这些基因组合的短期和长期后果。最终，我们需要确定哪些进化力量——例如，选择、遗传漂变、迁移——导致了受有性生殖影响的基因组合的形成。
