The proposed research will gain insight into one of the most fundamental yet puzzling questions in evolutionary biology and determine the generality of frequency-dependent selection as a mechanism for maintaining variation in asexual organisms. The results will have broad appeal, both internationally and nationally, and will also provide insight into why most species reproduce sexually. The results will also help in the development of two asexual species as environmental indicators by linking clones with specific environmental changes. These indicator clones could then be adopted by natural resource managers to monitor environmental pollution and contamination.

这项拟议的研究将深入了解进化生物学中最基本但令人困惑的问题之一，并确定频率相关选择作为维持无性生物变异的机制的普遍性。这一结果将在国际和国内产生广泛的吸引力，并将为大多数物种有性繁殖的原因提供洞察。通过将克隆与特定的环境变化联系起来，这一结果还将有助于发展两个无性物种作为环境指标。然后，自然资源管理者可以采用这些指标克隆来监测环境污染和污染。
