性别鉴定 - 维基百科,自由的百科全书

性别鉴定(英語:sexinggender identification)是生物学农学的技术手段,用于确定人、家禽家畜野生动物性别

对于两性异形的动物而言,可以根据形态学特征区分其性别,例如大多数哺乳动物可以通过外生殖器的差异来区分。[1]部分鸟类爬行动物两栖动物没有外部的性别差异,因而需要使用一些辅助技术进行性别鉴定。如在动物医学上,对于两性同形的鸟类可以在麻醉或束缚下依靠耳鏡英语Otoscope纤维内窥镜英语Fiberscope来通过内生殖器鉴定性别,也可以检验血液或粪便样本,通过两性的激素差异来判断性别。[2]而野生动物则可以依靠行为上的差异来区分。[3][4]养殖业中,可以翻开雏鸡的泄殖腔来鉴别其性别,也可以人为控制亲本的性别连锁基因,根据伴性遗传性状来确定子代的性别。[5]

随着分子生物学技术的发展,性别分子鉴定[6]或称分子性别鉴定[7](英語:molecular sexing)也相应地产生并应用在养殖业、生物学、法医学、考古学等领域。例如养殖场对雏鸡的性别鉴定、[5]采集野生动物的粪便进行性别鉴定、[8]鉴定非法狩猎的猎物的性别、[9]严重损毁的案件受害者遗体的性别鉴定、[10]对古人类残骸的性别鉴定[11]等。常用的分子标记物包括用于人及其它哺乳动物牙釉质基因英语Amelogenin#Application_in_sex_determinationSRYZFX/ZFY[10][12][13][14]用于鸟类的CHD1古颚类除外)、NIPBL(所有鸟类)、RASA1雉科)等。[15]
