1.DNA sequence variation in the same species of animals was only observed in human, donkey and mouse, and the number is less than 4 (1.3%), other animals showed no intraspecies variation.
同種動物不同個體間只有人、驢及小白鼠存在變異,最多有4個堿基變異位點(1.3%),其它動物未發(fā)現(xiàn)種內變異。

3.Research development of germplasm resources of Fructus Amomi was reviewed in the aspects of species resource, geographic distribution, intraspecies variation, and tissue culture.
從種類資源、產(chǎn)地分布、種內變異及組織培養(yǎng)等方面綜述了砂仁種質資源的研究進展。
4.The result also showed there was some difference in DNA content to the same ploidy between different species and different strains of the intraspecies.
同時還發(fā)現(xiàn),同一倍性的種與種之間,種內各株系之間,DNA的含量有一定的差異。
5.The competition, especially the intraspecies competition, is the mechanism and motivity of biological existence and evolution.
競爭,尤其種內競爭,是生物存在和進化的機制和動力。
