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(dòng)物不同個(gè)體間只有人、驢及小白鼠存在變異，最多有4個(gè)堿基變異位點(diǎn)(1.3%)，其它動(dòng)物未發(fā)現(xiàn)種內(nèi)變異。

2.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(dòng)物不同個(gè)體間只有人、驢及小白鼠存在變異，最多有4個(gè)堿基變異位點(diǎn)(1.3%)，其它動(dòng)物未發(fā)現(xiàn)種內(nèi)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(nèi)變異及組織培養(yǎng)等方面綜述了砂仁種質(zhì)資源的研究進(jìn)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(shí)還發(fā)現(xiàn)，同一倍性的種與種之間，種內(nèi)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(nèi)競爭，是生物存在和進(jìn)化的機(jī)制和動(dòng)力。

6.It was suggested that the geometry morphology plasticity highly responsed to intraspecies competition in different density.

高密度植株矮生長速率慢分枝短，不同密度種內(nèi)競爭對興安胡枝子幾何形態(tài)高度可塑。

7.By using different primers, the intraspecies variation of RAPD profiles was different.

采用不同引物進(jìn)行擴(kuò)增時(shí)種內(nèi)變異的程度有所不同。
