交配

MDH was applied to the studies of A.mellifera,which included several aspects as follows:the number of queen matings,labor division in honeybee societies,the analysis of genetic constitution in honeybee populations and so on.

东方蜜蜂（A.cerana F。）的MDH由S、F两个等位基因编码，也有报道它是单态性的。MDH在西方蜜蜂研究中应用较多，主要有处女王交配次数；蜂群中的劳动分工；蜜蜂种群遗传组成分析等。

Due to different interpretations, FFI should be written as "Female Family lnbreeding / linebreeding" for canine breeding.

根据不同的翻译解释，FFI应该被记载为母系家庭的同种异系交配。

The following are some examples of female family inbreeding / linebreeding pedigrees

以下就是母系同种异系交配的例子

Fist of all, lifespan of bucks has to be limited, the number of bucks should be enlarged and allocating mate has to be based on the Mate Selection Index. The risk of selection could be solved by linebreeding or import some bloodline from outside also.

可以采用的方法有：一是限定公羊的使用年限；二是扩大留种公羊的数量；三是使用交配选择指数控制选配。

Thus before undertaking Female Family Inbreeding / Linebreeding, the understanding of X-Chromosome and drawing correct of X-Chromosome are essential and breeders must determine a correct brood bitch for this purpose.

因此进行母系同种异系交配前，X染色体和绘制正确的X染色体图谱是必要的，繁殖者必须制作一个种母的图。

Animals of all sizes, from elephant to ant , all have procreational intercourse for their lifetime instead of recreational sex that humen beings can enjoy.

各种大小动物，大至大象，小如蚂蚁，终身都只是为了繁殖而交配；而不像人类能那样能以欢愉为目的享受性爱。

Its mating gear is called a worm gear, which is not a true helical gear.

其交配齿轮称为蜗轮，这是不是真正的螺旋齿轮。

Although Wallaces flying frog prefer to live high up, they must descend to near ground level to mate and to layeggs.

虽然华莱士树蛙喜欢生活在高处，但它们必须下至靠近地面的地方交配产卵。

Although Wallace's flying frog prefer to live high up, they must descend to near ground level to mate and to lay eggs.

虽然华莱士树蛙喜欢生活在高处，但它们必须下至靠近地面的地方交配产卵。

Although Wallace's flying frog prefer to live high up, they mustdescend to near ground level to mate and to layeggs.

虽然华莱士树蛙喜欢生活在高处，但它们必须下至靠近地面的地方交配产卵。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
