Note. Demographic data, total number of proteins, and peptide spectral matches observed in all 40 individuals. Mothers’ hair (n=8) had significantly higher number of proteins (p=0.001) and protein spectral matches (p=0.0004) compared to children’s hair (n=32). Related children (n=16, Cyan) are grouped with their mothers and unrelated children are listed below (n=16, Orange).
