Figure 2

Average level of risk-tolerance by genotype. Note: This figure shows the average level of risk-tolerance between the different genotypes. A higher level of risk-tolerance indicates the choice of a riskier lottery by participants in the lottery choice task. X/X, X/7 and 7/7 represent genotypes, with all alleles not 7R combined into the X allele. Samples from both risky and non-risky areas are pooled. Segments represent 95% confidence intervals. Student’s t-test * \(p<\) 0.1, **\(p<\) 0.05.
