野生动物学报, 2022 为了保证人工繁育的南白犀(Ceratotherium simum simum)种群能够健康长远发展,需要有详细准确的谱系记录,但是往往会存在子代亲生父亲不详的情况。通过亲子鉴定可以帮助确定子代亲生父本,从而获得准确的谱系记录。本研究在110只人工半散放南白犀群体中使用13个微卫星标记,对13个微卫星标记的多态性进行分析,计算非父排除概率和累积非父排除概率,结果显示:双亲已知时,13个位点的累积非父排除概率可达0.99以上,三联体父权分配时置信度可达到严格置信 ...

野生动物学报, 2021 蓝狐是圈养北极狐（Vulpex lagopus）的主要品种。因缺少科学有效的遗传管理，引进种兽后代逐年退化，造成反复引种的依赖性局面。为保持蓝狐种群的优良性状，开展科学选种选育、降低近交的概率，分析122只引进芬兰蓝狐的线粒体DNA DLoop区294 bp序列，结合已发表的野生、圈养北极狐种群单倍型数据进行母系追踪，应用11个微卫星位点的复合扩增对其中53只进行单亲亲权鉴定。结果表明：蓝狐种群仅有1种单倍型，血统单一，与瑞典养殖种群、西伯利亚野生种群关系密切。11个微卫星位点累计排除概率达到0 ...

中国人(广州地区)红细胞GPT遗传性多态现象的特点及血痕GPT的可测性研究 [PDF]
, 1986 谷丙转氨酶(Glutamic-Pyruvic Transaminase,GPT)是一种具有遗传性多态现象的细胞酶。它在机体各器官组织中广泛存在,尤以肝细胞含量最高。红细胞内GPT含量较少,但也有相当的活性。GPT有两种形式,分别存在于细胞质(可溶性型)和线粒体(线粒体型)之中。GPT分子由两个亚基组成,分子量约114 ...
