The development of DNA databases based on Y-chromosome analysis offers significant advantages for forensic identification, genealogical research, and population studies. Due to its paternal inheritance and minimal recombination, the Y chromosome provides a stable genetic marker for tracing male lineages across generations. Such databases facilitate the identification of male contributors in complex forensic samples, support the reconstruction of paternal ancestry, and contribute to anthropological insights into human migration. However, challenges including limited individual specificity, privacy concerns, and the need for robust data management systems must be addressed. This paper examines the potential applications, benefits, and limitations of Y-chromosome DNA databases, highlighting their role as a valuable complement to autosomal DNA profiling in various scientific and legal contexts.
