Genetic Fingerprinting and Its Evidentiary Significance

Genetic fingerprinting, also known as DNA profiling, is a powerful forensic tool used to identify individuals based on their unique genetic makeup. It works by examining specific regions of the DNA that vary greatly among individuals, often focusing on non-coding regions like short tandem repeats (STRs). Since these genetic markers are highly individualized, DNA profiling can provide a high degree of certainty in identifying or excluding potential suspects in criminal investigations.In addition to its forensic uses, genetic fingerprinting is also applied in paternity testing, identifying human remains, and verifying biological relationships in civil disputes. Its ability to match individuals to specific genetic traits makes it an essential and reliable tool in both criminal and civil litigation基因指纹技术（Genetic fingerprinting，又称DNA分型）是一类功能强大的法医学工具，可通过个体独特的遗传组成实现身份识别。该技术通过检测个体间差异显著的特定DNA区段展开工作，通常聚焦于短串联重复序列（short tandem repeats，STRs）这类非编码DNA区域。由于此类遗传标记具备高度个体化的特征，DNA分型能够在刑事调查中为认定或排除潜在嫌疑人提供极高的确定性。除法医学应用场景外，基因指纹技术还可应用于亲子鉴定、遗体身份识别，以及民事纠纷中的生物亲缘关系验证。其可将个体与特定遗传性状精准匹配的特性，使其成为刑事与民事诉讼中不可或缺且可靠的核心工具。
