Methods and Research Hotspots of Forensic Kinship Testing

Abstract

Kinship testing is widely needed in forensic science practice. This paper reviews the definitions of common concepts, and summarizes the basic principles, advantages and disadvantages, and application scope of kinship analysis methods, including identity by state （IBS） method， likelihood ratio （LR） method， method of moment （MoM）， and identity by descent （IBD） segment method. This paper also discusses the research hotspots of challenging kinship testing, complex kinship testing, forensic genetic genealogy analysis, and non-human biological samples.
