摘　　要：本实验观察了怀孕１０天以上的封闭群ＫＭ母鼠，近交系Ｃ＿（５７）ＢＬ／６ｊ母鼠，近交系ＢＡＬＢ／ｃ母鼠，杂交（ＤＢＡ／２×ＬＣＥＢ）Ｆ＿１母鼠和杂交（Ｃ＿（５７）ＢＬ／６ｊ×ＬＣＥＢ）Ｆ＿１母鼠的卵巢上黄体数和子宫内的胚胎数。在五组实验中观察结果（见表１，２）。在近交系方面，Ｃ＿（５７）ＢＬ／６ｊ实验组出现左右两边生殖器官的生育机能差异显著（Ｐ＜０．０１），在其他实验组中，左右两边生殖器官的生育机能差异不显著（Ｐ＞０．０５）。由于它们的遗传背景不同，在各自的繁殖基因控制下，可以出现这些遗传多态现象。Amount of corpora lutea in ovigerous and embrvos in uterus were ob-served to more 1han 10d pregnant of the female KM with randomly mated colonies,inbred female C57BL/ 6j,inbred female BALB /c,hybrid female(DBA / 2×LCEB)F1 and hybrid female(C5BL/6j×LCEB)F1 in mice on the investigation. Theirresults were observed in five experiment groups fsee table 1,2).The reproductive poten-tial showed a signiflcant difference(P< 0.01)between left and right reproductive or-gans in the inbred C57BL/6j experiment group.These reproductive potential differ-ences are not markedly different(P>0.05)between left and right reproductive organsin others experiment groups.Because their genetic backgrounds are different so thatgenetic polymorphisms were showed in themselves reproductive gene control.
