Dissertation Research: Selection on Floral Parameters in Mirabilis multiflora

植物种群的进化可能受到以下因素的影响 自然选择，基因流动（基因进入人口从 其他人群），和遗传漂变（由于小 人口规模）。 为了了解进化是如何进行的， 我们必须知道这些不同的力量是如何共同作用的。 所有 其中的一部分会受到个体传播基因的影响 传给下一代 然而，由于花粉从 植物到植物几乎是不可能遵循的， 很难确定哪些个体在提供基因 电泳技术使得 确定一个特定的人是否可能是一个孩子的父亲， 特别的种子 通过将这种技术应用于 一个群体中的所有个体， 个体为后代提供基因的能力。 了解种子的出身将有助于解释 不同的力量影响着种群的进化。 在 此外，关于基因如何在群体中移动的信息可以 应用于农业系统。 这些信息可能是 在培育特定性状或尝试 减少基因进出特定区域的数量， 区

The evolution of plant populations can be affected by natural selection, gene flow (genes entering the population from other populations), and genetic drift (chance events due to small population size). In order to understand how evolution proceeds, one must know how these different forces operate together. All of these are affected by which individuals are transmitting genes to the next generation. However, because movement of pollen from plant to plant is nearly impossible to follow, determination of which individuals are supplying genes is difficult. The technique of electrophoresis makes it possible to determine if a given individual could be the father of a particular seed. By applying this technique to seeds produced by all individuals in a population, a determination of which individuals are supplying genes to progeny can be made. Knowing the parentage of seeds will help explain how different forces affect the evolution of a population. In addition, information on how genes move through a population can be applied to agricultural systems. This informaton could be very beneficial when breeding for specific traits or when trying to reduce the amount of gene movement into or out of a particular area.
