遗传负荷理论的一种普适框架

遗传负荷表示种群由于遗传变异能力的存在而在平均适宜度上的损失，定量讨论各种遗传负荷，对研究现实发生水平上的物种进化具有重要意义，以往的遗传负荷理论从种群平衡出发，探讨现实发生水平上的物种进化，可是，进化是种群平衡的位移；这便构成了理论与现实之间的矛盾，为拓展以往的遗传负荷理论，给出了一个描述各种遗传负荷的普适理论框架，利用这个理论框架既能探讨平衡种群的遗传负荷，又能模写非平衡种群的遗传负荷及其变化，从而克服了以往的遗传负荷理论不能描述非平衡种群和不时与生物进化现实相悖的不足之处，为研究物种的进化提供了一种可靠的模拟方法。

A General Frame of Theory on Genetic Load

Genetic load expresses the loss in mean fitness of a population because of the genetic variability present. The quantitative discussion of various genetic loads is provided with important meaning for research into evolution of species on realistic level. The past theory on genetic load starts off with equilibrium of population to investigate the evolution of species on realistic level. However, the evolution is a displacement on equilibrium of population. This is just made up of a contradiction between theory and praxis. We branch out the past theory on genetic load, and give out a general theoretic frame describing the various genetic loads. By the use of this theoretic frame the genetic loads in an equilibrium population can be represented, and the genetic loads in a non equilibrium population and their change can also be simulated. Thus this theoretic frame overcomes the shortcoming of past theory on genetic loads, which can't describe non equilibrium population and conflicts with praxis of biological evolution sometimes, and offers a sort of credible simulation methods for research into evolution of species.
