Genetic diversity and phylogenetic relationship in goldfish were examined using mitochondrial D-Loop partial sequences at eight representative varieties of goldfishes and wild crucian carp. The eight representative varieties were Red Common Goldfish, Red Fantail, White Oranda with Red Carp, White Pearlscale, Red Tigerhead, Black Moor, Red Moor with Butterfly Tail and Red Bubble-eye with Dorsal Fin. 699 base-pair nucleotide sequences of Mitochondrial D-Loop were examined and analyzed for genetic polymorphism, Sequences data showed that all 129 sequences were grouped into 17 haplotypes. Nine representative varieties shared same haplotype. Five representative varieties of goldfishes had haplotypes respectively.

采用PCR技术扩增了红草金鱼，红文鱼，红顶白高头，白珍珠，红狮头，红龙睛蝶尾，墨龙睛，红水泡八个品种金鱼和野生鲫线粒体DNA的D-Loop区部分序列，PCR产物经纯化、测序、同源序列比对后获得长度为699bp的核苷酸序列，在129个样本中共检测到了17个单倍型，9个品种共享1种单倍型，5个品种的金鱼(BM， MB， WR， RF， RC)检测到各自独有的单倍型。

In this thesis, the integrated cDNA sequences of hira genes have been isolated from full-matured ovary SMART cDNA library of gynogenetic gibel carp and bisexual coloreded crucian carp by PCR and RACE-PCR.

本研究通过PCR和RACE的方法，分别从天然雌核发育银鲫和两性生殖彩鲫成熟卵细胞的SMART cDNA文库中克隆出hira全长基因。

The results showed that: The number of loci detected in the German mirror Carp, Japanese crucian carp and F1 were 200、207、218, and the number of polymorphic loci were 63、66、72,and the percentage of polymorphic loci were 31.5%、31.9%、33% respectively. The percentage of polymorphic loci of F1 was considerately higher than that of the parents indicating the rather great genetic variations within the 3 populations.

结果表明：在德国镜鲤、日本白鲫、F1中检测到的位点数分别为200、207、218，其中多态性位点数分别为63、66、72，多态位点比例分别为31.5%、31.9%、33%。F1多态位点高于父母本，表明它的遗传多样性和变异水平最高。

The random amplified polymorphic DNA technique was applied to the genetic analysis of Japanese crucian carp ,German mirror carp and their filial generations for using of 24 random primers selected.

摘 要：利用筛选的24个随机引物，对日本白鲫×德国镜鲤( Cyprinus carpio var specularis Lacepede)杂种一代及双亲进行RAPD分析。

The corresponding genetic distance is 0.3068, 0.2041(GMC and F1) and 0.1961(JCC and F1) respectively. The genetic distance between German mirror carp and Japanese crucian carp is the largest.

三个群体间的遗传距离分别为0.3068、0.2041（德国镜鲤和F1）、0.1961（日本白鲫和F1）。

This suggests that CaHIRA plays a role in the early embryo development and the late stages. The different expression characters of hira gene in these fish species may be related to the different reproduction models. The research on Drosophila has indicated hira gene related to sperm nucleus decondensation during fertilization. The high expression of hira gene before fertilization is prepared for the sperm nucleus decondensation and the formation of male prenucleus because colored crucian carp is bisexual reproduction. However, the sperm nucleus is not decondensated during the fertilization and is only to activate egg nucleus in gynogenetic gibel carp.

在彩鲫中，从未受精卵到胚胎发育的各个时期均可检测到表达，但表达量发生明显变化，受精后表达量迅速下降，直到原肠胚期表达量有所上升，并一直保持到出苗。hira基因在两亲缘种成熟卵子受精前后表达情况不同，可能与两种鱼不同的生殖方式有关。
