  "abstract": "This commentary critiques Nogueiro et al. (2015), who used Y chromosome and mitochondrial DNA haplotype data from contemporary Iberian and non-Iberian populations to explore a diagnostic genetic signature of Portuguese \"crypto-Jews.\" The authors identify two main weaknesses: (1) the matrilineal and patrilineal markers reviewed are methodologically inadequate as \"reliable Jewish ancestry predictors\" due to haplotype polyphyly and molecular clock ambiguity — many ostensibly \"Jewish\" haplotypes are",
