随机交配群体

It is the differentia that three kinds of genotypes frequency of panmixia parts of common population are constant in every generation,but variable in selfing part.

不同的是普通群体随机交配部分的3种基因型频率在各世代是固定的量，自交部分的3种基因型频率是变量。

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。

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。

By the contrast between common population and inbreeding population, we know that the sameness of them are they all take the population for the synthesis of panmixia and selfing or inbreeding.

通过普通群体与近亲交配群体的比较，群体在非平衡条件下，普通群体与近亲交配群体相同的是都把群体作为随机交配和自交或近亲交配两部分的合成群体。

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。

Tenth. A series of mathematical model of genetic mechanism of common population have been established,they are mathematical description of genetic mechanism of common population, so the population that the population genetics researching have extended from panmixia population, inbreeding population,selfing population to common population. It will start the new research territory of population genetics and promote its development.

本文建立了普通群体遗传机制的一系列数学模型，这是对普通群体遗传机制的数学描述，它使群体遗传学所研究的群体由随机交配群体、近亲交配群体、自交群体扩展到普通群体。

The panmixia hypothesis--that all European eel migrate to the Sargasso Sea for reproduction and comprise a single, randomly mating population--is widely accepted.

欧洲鳗鲡随机交配的假说—所有的欧洲鳗鲡个体都洄游到Sargasso海进行繁殖，组成一个单一并随机交配的群体—一直被广泛接受。

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。

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。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
