NSF Minority Postdoctoral Research Fellowship for FY 1998

这一行动为1998年美国国家科学基金会少数民族博士后研究奖学金提供资金。该奖学金支持种群生物学领域的研究和培训。这项研究和培训计划的题目是“寄生虫能否解释有性重组的维持？”理论模型表明，有性重组是有利的，因为它打破了过去选择所固定的基因联系，使生物体能够适应当前的环境。该项目研究寄生虫选择是否导致基因关联，性重组是否增加对寄生虫的抗性，以及不同寄生虫是否选择相似或不同的宿主基因型。这项研究可以帮助确定遗传多样性对共同进化和农业和保护政策制定的重要性。

This action funds an NSF Minority Postdoctoral Research Fellowship for 1998. This fellowship supports research and training in the area of population biology. The research and training plan is entitled can parasites explain the maintenance of sexual recombination? Theoretical models suggest that sexual recombination is advantageous because it breaks gene associations fixed by past selection, allowing organisms to adapt to their present environment. This project investigates if parasite selection causes gene associations, whether sexual recombination increases resistance to parasites and whether different parasites select for similar or different host genotypes. This research can help determine the importance of genetic diversity to coevolution and the development of agricultural and conservation policies.
