The genetic variation among the natural populations of ginkgo revealed by Nei"s analysis , Shannon"s information index analysis and analysis of Molecular Variance ISSR :Gst=0.1955,(= 0.1903,φST= 17.63%;RAPD:Gst=0.2882,= 0.2949,φST=36.69% was greater than other kinds of anemophilous plants. The genetic differentiation among populations might be caused by human selective pressures and barriers of geography.

In the 2A1 distorted trigonal bipyramid structure ,the single non equivalent Ga atom has the population of 4s 4p ,while the two equivalent Ga atoms have the population of 4s 4p .this compares with a Ga population of 4s 4p in the undistorted D3h structure ,hence the jahn-teller distortion causes depletion of the charge density on the 4s orbital of the non-equivalent Ga atom, and enhancement of charge density on the 4s orbital for the two equivalent atoms .an opposite trend is observed for the 4p orbitals of these Ga atoms .the P population for the two equivalent atoms is 3s 3p .the populations of the other 2B1 state with the edge-capped tetrahedral structure are similar with the exception that all three Ga atoms have similar but not identical populations .
在2A1被变形的三角bipyramid结构,唯一非等效Ga原子有4s 4p的人口,而二个等效Ga原子在未变形的D3h结构有4s 4p 。this的人口和4s相比4p的Ga人口,因此jahn出纳畸变在non-equivalent Ga原子的4s轨道导致电荷密度的取尽,并且电荷密度的改进在4s轨道为二个等效原子。an在趋向对面对这些Ga原子4p轨道被观察。the人口为二个等效原子是另一个2B1状态3s 3p 。the人口与边缘加盖的四面体结构是相似的P 除之外全部三个Ga原子有相似,但不相同人口。

Low genetic variation has probably resulted from the refugial nature of these populations since the last glaciation rather than from recurrent pollen dispersal between Chilanshan and Alishan populations of these 2 Chamaecyparis species. Two Hinfl restriction site differences were found in the trnV-trnM intergenic spacer between C. formosensis and C. taiwanensis. Fragment length difference as well as point mutations in the petG-trnP intergenic spacer between C. formosensis and C. taiwanensis were also found.
如此低的遗传变异可能是因为现今之红桧与台湾扁柏族群为冰河期存在之大族群的残留小族群,而未必是花粉散播所提供之基因交流极为频繁所造成。trnV-trnM基因间区间序列在红桧与台湾扁柏两者间有两个HinfI之酶切点之差异,在PetG-trnP基因间区间序列也发现台湾扁柏与红桧之间有限制酶片段长度及其他点突变。
