The focus of this study was to examine the consequences of five sequential generations of enforced selfing and outcrossing in two annual populations of the mixed-mating Mimulus guttatus. Our primary goal was to determine whether purging of deleterious recessive alleles occurs uniformly between populations and among families, and thus gain insights into the mode of gene action (dominance, overdominance, and/or epistasis) governing the expression of inbreeding depression at both the population and family levels across the life cycle.
本研究的重点是检验在一年生的混合交配型沟酸浆（Mimulus guttatus）的两个种群中连续五代强制自交和异交的后果。我们的主要目标是确定有害隐性等位基因的清除在种群之间和家系之间是否均匀发生，从而深入了解在整个生命周期中，控制种群和家系水平近亲繁殖衰退表达的基因作用模式（显性、超显性和/或上位性）。
