Sažetak
Darwin’s tubercle (DT) is a minor auricular trait showing wide inter-population variation and non-Mendelian patterns of familial aggregation. This study examines sex-biased parent–offspring aggregation of DT in an Eastern Indian tribal population (Lodha PVTG), using 416 parent–offspring pairs. Significant associations were observed across all parental pathways (Chi² = 28.45–86.49; p < 0.001), with strongest aggregation in father–son pairs. The findings support autosomal expression with sex-specific penetrance and developmental modulation.
