适合度和重组率之间的负相关似乎存在于各种生物中。在这篇文章中，我们认为这种相关性可能在复杂性状的进化中发挥重要作用。我们在一个简单的模型中研究了这种适应度相关重组（FAR）的影响。双位点确定性模型，以及在多位点NK崎岖的适应性景观。在这两种模型中，与均匀速率重组相比，FAR导致更快的适应和更高的平均种群适应度。
A negative correlation between fitness and recombination rates seems to exist in various organisms. In this article we suggest that a correlation of that kind may play an important role in the evolution of complex traits. We study the effects of such fitness-associated recombination (FAR) in a simple. two-locus deterministic model, as well as in a multi-loci NK rugged adaptive landscape. in both models studied, FAR results in faster adaptation and higher average population fitness, compared with uniform-rate recombination.
