Figure 3. The concentrations of GSH, GSSG, Ehc and tGSH within RBCs behave as heritable traits.

Figure 3

Heritability was estimated using the method of Newman, Freeman, and Holzinger. The estimated heritability for GSH is 57 %, for GSSG 51 %, tGSH 63 %, and Ehc 70 van ‘t Erve et al. GSH is heritable in RBCs Page 20 of 29 %. The heritability for height (96 %) and BMI (63 %) were used as markers to compare our study population to other published reports on this established heritable trait (dashed boxes, height 87 – 93 %, BMI 39 – 91 %) [28].
