摘要
利用寡核苷酸指纹探针 LZF- 检测了成都大熊猫繁育研究基地仿生态圈养场小熊猫种群全部 2 2只个体的 DNA指纹 ,检测结果表明其遗传多样性参数如下 :( 1 )各体间 DNA指纹图的相似性为 0 .1 72 ;个体 A的指纹谱带在个体 B中出现的概率为 0 .1 80 6。 ( 2 )圈养种群的等位基因频率为 0 .0 94 8,杂合率为 90 .52 %。 ( 3 )
Using the method of labeling oligonucleotide probe LZF Ⅰ,we determined DNA fingerprints of 22 captive red pandas in our base to measure the genetic diversity of the captive population.The results were as follows similarity coefficient of DNA fingerprinting bands each individual was 0.172.Probability of fingerprinting bands of individual A which appeared in individual B was 0.1806.Mean allelic frequency of the captive population was 0.0948 and heterozygous ratio was 90.52%.Introducing subspecies fulgens to the captive population was the main factor to influence its genetic diversity.
