I think, and I am no expert in this.. but a genetic correlation is between two traits. Negative genetic correlation: if X increases then Y decreases Positive genetic correlation: if X increases so does Y I think each trait on the graph should be paired with educational attainment as a second trait. So: GeneticCorrelation(Cigarettes, EDUCATION) -> Negative GeneticCorrelation(Longevity, EDUCATION) -> Positive My take is this: The chart shows the relationship between the genes responsible for higher education X and {insert trait} = Y, where X is further split into IQ and non-IQ..
