随机交配的

The research by compute r simulation analysed the possibility of long-time conserving heterozygote in co long.

本文运用计算机模拟的方法，在随机交配、随机留种的情况下，分析了群体中长期保存杂合子的可能性。

Generally, whether the panmixia ratio is large or small, the population reaches to equilibrium after 1-10 generations.

普通群体依据随机交配率大小的不同，趋近平衡的时间不同。

When the panmixia ratio vary from 0 to 1, its influence on the genotype frequency are lessening, as for inbreeding coefficient, it is constant.Ninth.

并且随机交配率从0到1对基因型频率影响的程度由大逐渐变小，近交系数对基因型频率影响的程度始终一样。9。

Mathematical model 3.7, 3.16 and 3.30 are the mathematical model of a equilibrium population, and they can be converted into mathematical models of panmixia population and nonequilibrium selfing population.

它可以转换为随机交配群体的数学模型和非平衡自交群体的数学模型。

When population are in noneequilibrium, if we know the genotype frequency of one generation of common population, the genotype frequency of the next or any generation can be calculated on the basis of the panmixia ratio and gene frequency directly.

群体在非平衡条件下，如果已知普通群体某一世代的基因型频率，根据随机交配率、基因频率可直接推算下一代或任一世代的基因型频率。

To date, the panmixia hypothesis has remained unchallenged: genetic studies realized on eel's mitochondrial DNA failed to detect any genetic structure; and a similar lack of structure was found using allozymes, with the exception of clinal variation imposed by selection.

到目前为止，随机交配假说尚未得到挑战：通过线粒体研究未发现鳗鲡存在遗传结构，而利用同工酶也得到缺乏遗传结构的相似观点，而因选择引起的渐变群变异是例外。

Theeffective size of populations under maximum negative or positive assortive mating is larger thanrandom mating of selected parents.

同质和异质选配情况下，群体有效大小较选择的亲本随机交配要大，特别是异质选配。因此，采用异质选配，可以使选育与保种有机地结合起来。

So level of random breading were high between different individuals in the populations.

种豚草的异交率分别为0.5123和0.6393，其种群内植株间随机交配程度较高。

The average panmictic heterozygosity ( hs = 0.3037 ± 0.0058) in the Gongliu population was the highest, followed by the Huocheng population.

巩留群体、新源群体、霍城群体和裕民群体分别扩增了180、169、178和165条多态性带，巩留群体的随机交配杂合度（ hs = 0.3037 ± 0.0058）最高，其次为霍城群体。

If the butterflies continue to mate randomly, the frequencies of black-winged, grey-winged, and white-winged butterflies in the next generation will be

假如此种蝴蝶可继续随机交配，其下一代翅的颜色，将呈现下到哪种表现型频率

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
