This paper also discusses the research hotspots of challenging kinship testing, complex kinship testing, forensic genetic genealogy analysis, and non-human biological samples.

Key words: forensic genetics, kinship, identity by descent, identity by state, likelihood ratio, method of moment, challenging biological materials, pedigree analysis, review
