| 3. | Cytogenetic studies were made on several hybrid scallops using the karyotype method . hybridizations between chlamys farreri and patinopecten yessoensis , c . farreri and chlamys nobilis were studied
本论文在染色体水平对虾夷扇贝栉孔扇贝杂交以及栉孔扇贝华贵栉孔扇贝正反交等几个扇贝杂交组合进行了细胞遗传学研究。 |
| 4. | With the selected outgroup - chlamys farreri , the phylogenetic trees suggested that zhejiang population has differentiated . 3 . in pb - pa and y1 - p0 families of argopecten irradians , 12 and 10 rapd primers were selected , which
在海湾扇贝pb - pa与y1 - p0家系中，分别筛选出12和10条引物，其扩增出的产物在双亲中呈现多态的片段。 |
| 5. | Results also showed that lectins such as pha did not have distinct influence on increasing of metaphase of scallop . intergeneric hybridization between patinopecten yessoensis and chlamys farreri yielded hybrids which can survive to adult
本论文还对pha等外源凝集素对扇贝成体组织染色体的制备的影响进行了研究，结果未观察到pha对增加扇贝染色体分裂相有显著的影响。 |
| 6. | Chlamys farreri , which belongs to mollusca , bivalvia , pterioidae pectinidae , are widely distributed on the china from donghai sea to bohai sea , korea and japan . this species has been the main aquacultrue shellfish for many years in northchina
利用同工酶技术，对中国栉孔扇贝和日本栉孔扇贝的遗传差异进行了比较分析，并对它们的正反交后代的酶表型及遗传型进行了分析，探讨了亚种间杂交的机制。 |
| 7. | The same phenomenon was observed in interspecific hybridization between chlamys farreri and chlamys nobilis . the karyotypes of adult hybrids and their parents were analyzed and compared . the chlamys nobilis ' s diploid chromosome number is 2n = 32 , karyotype consists of 6m + 26t , nf = 38
对该杂交组合的亲本华贵栉孔扇贝的染色体核型分析表明，华贵栉孔扇贝杂交扇贝的细胞遗传学研究共有zn = 32条染色体，核型公式为2n = 32 = 6m + 26t ，染色体臂数nf = 38 。 |
| 8. | The results showed that hybrids from hybridization between chlamys farreri and chlamys nobilis had 35 chromosomes and uniform karyotype . on the other hand , 1 / 3 of hybrids from hybridization between chlamys nobilis and chlamys farreri had 35 chromosomes , another 1 / 3 had 38 . results showed polymorphism in karyotypes of hybrids from latter hybridization
与此相对应，对正交子代染色体的统计结果表明，约l / 3的染色体分裂相拥有35条染色体，而1 / 3的染色体分裂相拥有38条染色体;正交子代的染色体核型也具有多态性，不能统一。 |
| 9. | Rapd ( random amplified polymorphic dna ) technique was used to study the genetic structure and genetic differentiation of the natural population and the hatchery stock of chlamys farreri . amplifications with 20 10 - base primers under predetermined optimal reaction yielded 153 reproducible amplified fragments ranging from 200 to 3000bp . the mean proportions of polymorphic amplified fragments of natural population and the hatchery stock were 73 . 2 % and 70 . 6 % respectively , and the mean hetreozygosities of them were 0 . 27 and 0 . 26 respectively
在对20个野生栉孔扇贝和20个养殖栉孔扇贝的基因组dna的检测中， 20个随机引物共扩增出153条清晰可分辨的dna片段，片段大小在200 3000bp之间，其中野生种群和养殖群体多态性片段分别为112和108条，多态位点比例分别为73 . 2 %和70 . 6 % ，杂合度分别为0 . 27和0 . 26 。 |
| 10. | Crossbreeding of chlamys farreri were performed using the parent scallops from the korea wild population ( k ) , china cultured stock ( c ) and the survived individuals in epedimic waters in culture area of china ( cs ) . four crosses , k k , k c , k cs and c c , were constructed . the index of growth performance of their progenies such as the length and width of the shell and the individual weight were measured for heterosis study
用来自韩国野生的栉孔扇贝和中国养殖的栉孔扇贝以及发病区存活的个体作为亲本，构建韩国野生韩国野生、韩国野生中国养殖、韩国野生中国养殖发病区存活个体以及中国养殖中国养殖共四个交配组合，通过对f1代个体壳宽、壳高和体重的测量比较不同群体的生长情况。 |
