  1. So must use information theory method depict and abundant the genetic diversity index system. in addition to, the introduce of molecule biology technology and the research of nucleotide sequence evolutive give a new method for population genetic, so must do deeply research about the analysis method of dna sequence data = the research main about the follows : there are three parts about the information model of population genetic : one about the shannon information entropy property of equilibrium population and the entropy change in the process of establish equilibrium ; another research is about the diversity measure - ment of genetic variation ; lastly, research the shannon information measurement about the disequilibrium gene variation. the result is : 1 to a definite gene distribution, the genotype entropy reach the maximum at the equilibrium population, the process of population from disequilibrium to equilibrium, the entropy get large and large

    此外，分子生物技術的介入及核苷酸序列進化的研究都為群體遺傳學的深入研究提供了新的途徑，但關于dna序列數據的分析方法需要作進一步的研究。本研究主要體現在以下幾個方面： （一）關于群體遺傳學的信息論模型研究，主要分為三部分內容：一是群體平衡的shannon信息熵的性質和群體平衡建立的熵變性質；二是群體遺傳多樣性測度的研究；三是非平衡群體的基因變異測量shannon信息量的方法研究。得到了如下結論： 1 、平衡群體的shannon信息熵最大，群體平衡的過程是熵的增大過程。
  2. Cytological genetic analysis revealed that the chromosome number of gynogenetic grass carp is 48 and the karyotype is 18m + 24sm + 6st, fundamental arm number ( nf ) is 90, just as those of the common grass carp

    此外，對雌核發育草魚細胞遺傳學分析證實所得雌核發育草魚的染色體數目為48條，其核型公式為18m + 24sln + 6st ;臂數為哪習o 。
  3. Though the technique of nuclejc transformation in plants has been developed and used widely, some problems in genetic information have not been resolved. for example, because the nucleic genome is so big and complicated that the integration sites and copies of foreign gene can not be controlled accurately, the expression of transferred genes is inefficient as a result of gene silencing or position effect. in nucleic transformation, furthermore, the transfer of multigene is difficult, and only after the prokaryotic genes undergo modification are they expressed in high plants

    植物的細胞核轉化技術已發展成熟並得到廣泛應用，但核基因組的遺傳轉化仍存在一系列至今尚未解決的問題：例如由於核基因組大，背景復雜，外源基因的整合位點和整合的拷貝數難以人為控制，造成鄭州大學2003年博士學位論文杜氏鹽藻（ dunaliellasalina ）葉綠體轉化研究外源基因表達效率低，容易出現基因失活、基因沉默、位置效應等現象;同時轉入多個基因時操作步驟過于復雜，所表達的原核基因必須經過修飾改造，環境安全難以保證等。
