MCF: Patterns of Parenthood in a Hybrid Swarm

种间杂交在植物中很常见， 重要的进化后果。 因为它的进化 重要的是，植物杂交一直是 在宏观层面上进行了大量的实证研究， 特别是在系统学和系统发育重建方面。 虽然杂交是微进化的结果， 过程，以前的研究没有测量 原位杂交过程的微进化动力学。 这项研究的主要目标是进行这样一项研究， 测量遗传、空间和性别参数， 测定种间杂交率和双种率 南方鼠尾草属天然杂种群体的基因流 加州。 主要研究者将通过以下方式获得这些数据： 利用多态性遗传标记进行亲子鉴定， 鉴定由所有个体在同一种植物中所结种子的花粉亲本 蜂拥而至 由此产生的数据将揭示 这一重要进化力量的微观进化动力学。

Interspecific hybridization is common in plants and can have important evolutionary consequences. Because of its evolutionary significance, hybridization in plants has been the subject of considerable empirical study at the macroenolutionary level, particularly in systematics and phylogeny reconstruction. Although hybridization is the result of microevolutionary processes, previous studies have not measured the microevolutionary dynamics of the hybridization process in situ. The primary goal of this research is to conduct a such a study, measuring the genetic, spatial, and gender parameters that determine the rate of interspecific hybridization and bi-species gene flow in a natural hybrid swarm of Salvia in Southern California. The Principal Investigator will obtain these data by using polymorphic genetic markers for paternity analysis, and identifying pollen parents of seeds set by all individuals in the swarm. The resultant data will shed light on the microevolutionary dynamics of this important evolutionary force.
