随机交配

F1公猪5头，母猪23头，随机交配产生287头F2个体。

287 F_ 2 offspring were born by random mating from five boars and twenty three sows .

在随机交配系统中，构建了包括加×加上位性的育种值，作为MAS中个体选择指标；

In random mating system , breeding value , extending its original connotation with inclusion of additive x additive epistasis , is proposed as a measure used in selection .

10个地方猪种的群体近交分析ZI随机交配群体的近交系数都比较低，贵州小型香猪的最高，为0.1992，荣昌猪的最低，为0刀727。

2.1 The inbreeding coefficients of the random mating populations were lower . That of Guizhou miniature pig was the highest ( 0.1992 ) in the 8 breeds , and Rongchang the lowest ( 0.0727 ) . The inbreeding degree of miniature pigs was higher than other 5 local pigs .

大多数关于种子园理论，是以假定能发生随机交配和自花受精而不会成为严重问题为依据的。

Most seed orchard theory is based on the assumption that panmixis will occur and that selfing will not be a serious problem .

究其原因有随机交配发生偏移、遗传漂变及选择等因素，其中选择所造成的影响最大，其次为随机交配发生的偏移以及遗传漂变。

The reasons may be that the excursion occurred in random mating , the random genetic drift and breeding was existed in 6 populations .
