“…Both methods may provide similar accuracy when the same SNP panel is used [15] although ML methods require a higher computational cost and expertise. Indeed, several articles compared and introduced different classi ers for FDP analysis [12,48,67,68,70,117,205,206,217,227,252,299,327].…”

In the past few years, forensic DNA phenotyping (FDP) has attracted a strong interest in the forensic research. Among the increasing publications, many have focused on testing the available panels to infer biogeographical ancestry (BGA) on less represented populations and understanding the genetic mechanisms underlying externally visible characteristics (EVC). However, there are currently no publications that gather all the existing panels limited to FDP and discuss the main technical limitations of the technique. In this review, we performed a bibliographic search in Scopus database of FDP-related literature, which resulted in a total of 48, 43 and 15 panels for BGA, EVC and both BGA and EVC inference, respectively. Here we provide a list of commercial and non-commercial FDP panels and the FDP limitations regarding the lack of harmonization in terms of terminology (i.e., categorization and measurement of traits) and reporting, the lack of genetic knowledge and environment influence to select markers and develop panels, and the debate surrounding the selection of genotyping technologies and prediction models and algorithms. In conclusion, this review aims to be an updated guide and to present an overview of the current FDP-related literature.

“…However, the selection of the best SNPs for EVC determination seems to be highly population-dependent, suggesting that panels for eye-colour prediction should be adjusted for different geographical regions: for instance, a relevant effect on eye colour was observed for rs1408799 in the Polish population, and for rs916977 in the Czech population, while rs1800416 was found to be significantly associated with eye colour only in the Brazilian population [24,60,70].…”

“…However, especially for eye and skin colour, one of the main approaches consisted of seeking advice from specialists in the sector, usually ophthalmologists and dermatologists, but also anthropologists with experience in phenotyping [24,26,38,61,72,73,75,87,90]. In a few cases, phenotype data were collected from participants themselves, through self-declaration or self-administered questionnaires [60,64,69,92,93] or were not known and just inferred from ethnic background [53,65]. Occasionally, the method used was not indicated [41,60,65,74,76].…”
