1) Artificial tetraploid crucian carp
人工四倍体鲤鲫
2) allotetraploid hybrids
异源四倍体鲫鲤
1.
Both the males and females of the tetraploids with 200 chromosomes were obtained from the offsprings (G_1×AT) produced by mating the eggs of G_1 with the diploid sperms from the allotetraploid hybrids.
二倍体雌核发育第 1代 (G1)产生的二倍体卵子经紫外线灭活的散鳞镜鲤精子诱导 ,无需染色体加倍处理 ,发育成二倍体雌核发育第 2代 (G2 ) ;G1 产生的二倍体卵子与雄性异源四倍体鲫鲤 (AT)产生的二倍体精子结合 ,形成新型两性可育的异源四倍体鲫鲤 (G1 ×AT)。
2.
A new type of triploid crucian carp was generated by mating the males of the allotetraploid hybrids of red crucian carp (Carassius auratus red var.
三倍体鲫鱼体色为青灰色 ,单尾 ,具有一些介于其父母本———异源四倍体鲫鲤和红色双尾金鱼之间的外形特征 ,如具有 1对肉眼不易观察到的短须 ,侧线鳞式为 31 6 7,背鳍为 18,体高 体长之比为 0 5 ,比湘云鲫的体高 体长之比 (0 4 1)有明显的增加。
3.
The early embryonic development of triploid crucian carp which was generated by mating the males of the allotetraploid hybrids of red crucian carp(Carassius auratus red var.
以异源四倍体鲫鲤为父本,二倍体金鱼为母本通过倍间杂交形成三倍体鲫鱼。
3) Allotetraploid fish
异源四倍体鲫鲤
1.
In the present study, a series of molecular biological techniques including subcloning of polymerase chain reaction(PCR) product, RT-PCR, Northern blot, Southern blot, were used to analyze Sox9 genes related to sex determination in allotetraploid fish.
本文综合运用PCR亚克隆、RT-PCR以及Northern、Southern杂交等分子生物学技术，对异源四倍体鲫鲤性别决定相关基因Sox9进行了研究，主要结论如下： (1)用特异于HMG-box(high mobility group-box)保守区的简并引物扩增了异源四倍体鲫鲤及其原始亲本(红鲫和鲤鱼)的Sox基因。
5) Artificial multiple triploid carp
人工复合三倍体鲤
补充资料：人工受精与人工授精
人工受精与人工授精
artificial fertilization and artificial insemination
我国学者把“人工受精”与“人工授精”两名词区别开来：前者指人工体外受精而言，后者指把精液注入到妇女的阴道或宫颈管、宫腔内，使精、卵在体内相遇。人卵体外受精与胚胎移植后出生的婴儿俗称试管婴儿。
