Charles Darwin recognized that flowering plants have an unrivalled diversity of sexual
systems. Determining the ecological and genetic factors that govern sexual diversification in …

Surveys of nucleotide diversity are beginning to show how genomes have been shaped by
evolution. Nucleotide diversity is also being used to discover the function of genes through …

摘要植物繁育系统是当今进化生物学研究中最为活跃的领域. 繁育系统是指代表所有影响后代
遗传组成的有性特征的总和, 主要包括花形态特征, 花的开放式样, 花各部位的寿命 …

The study of variability within species is important to all biologists who use genetic markers.
Since the discovery of molecular variability among normal individuals, data have been …

• Premise of the study: Analyses of genetic structure and phylogenetic relationships
illuminate the origin and domestication of modern crops. Despite being an important …

Varying degrees of reduction of genetic diversity in crops relative to their wild progenitors
occurred during the process of domestication. Such information, however, has not been …

The profound effects of inbreeding and other non-recombining breeding systems on genetic
variability and molecular evolution are now beginning to be understood. Theoretical models …

Natural selection and genetic linkage cause DNA segments to have genealogical histories
resembling those of the selected sites. When a polymorphism maintained by selection is old …

The postgenomics era will bring many changes to ecology and evolution. Information about
genomic sequence and function provides a new foundation for organismal biology. The …

A fundamental challenge in population genetics and molecular evolution is to understand
the forces shaping the patterns of genetic diversity within and among species. Among them …
