With the advance of molecular biology, DNA analysis technology has been widely applied in forensic science. Non-human DNA analysis can be used in some special cases and has unique forensic value to provide investigation clues and trial basis. Animal DNA typing plays a more prominent role in the detection of all kinds of non-human DNA related cases and is the main content of forensic non-human DNA analysis. This paper reviews the development history, present situation, advantages and disadvantages of animal DNA typing according to its technology, characteristic, challenges facing forensic science application scenarios, and also its future development.
随着分子生物学的进展，DNA分析技术在法庭科学中得到了广泛应用。非人源DNA分析可以应用于一些特殊案件，在提供侦查线索和审判依据方面具有独特的法医学价值。动物DNA分型在各类非人源DNA相关案件中作用突出，是法医学非人源DNA分析的主要内容。本文就动物DNA分型技术和特点、法医学应用场景中面临的挑战，综述了其发展历史和现状、优势与不足，并展望了其未来的发展。.
