指纹具有特异性、稳定性和遗传性,因而很早即被应用于个人识别。但对其遗传性的研究则远远落后。1880年Forlze首先提出指纹具有遗传性,但由于指纹遗传的复杂性及当时遗传学水平所限,许多学者对此持反对意见。此问题争论了很久。人们通过对孪生儿指纹的研究,对指纹种族差异及亲子间相关性的研究,逐渐发现指纹遗传是事实。指纹遗传是从如下几个方面研究的。 Fingerprints are specific, stable and hereditary and thus have long been used for personal identification. However, its genetic research is far behind. Forlze first proposed fingerprinting in 1880, but due to the complexity of fingerprinting and genetic limitations, many scholars disagreed. This issue has been debated for a long time. People through the twin fingerprinting research, fingerprinting ethnic differences and parent-child correlation studies, and gradually found that fingerprinting is a fact. Fingerprinting is studied from the following aspects.
