Eye h2 95% CI e2 95% CI Age 95% CI
Right0.780.73–0.820.190.15–0.230.030.008–0.06
Left0.800.75–0.840.180.15–0.230.020.004–0.05
  • h2 = proportion of variance due to additive genes, e2 = proportion of variance due to individual environmental effects, age = proportion of variance due to age effect, 95% CI = 95% confidence interval.
