Genetic gains (a) and genetic variance (b) trends for a simulated wheat line breeding program (with 100 independent simulations). The red line represents the baseline breeding scheme, the blue line represents the evolutionary algorithm (EA) genetic gain breeding scheme, and the green line represents the EA balanced gain breeding scheme (a breeding scheme which aimed to maintain a balance between genetic gains and genetic diversity).

Cumulative release of phosphate (P) during dissolution of hydroxyapatite with and without the addition of acetic acid (A), fumaric acid (B), maleic acid (C), tartaric acid (D), tricarballylic acid (E), and citric acid (F). The dissolution occurred at pH 8.01. Blue arrows indicate that the arrangement ("molecular configuration") of carboxylic acid functional groups is more important to the weathering process than their concentration (brackets).
