Traits

• A quantitative trait is produced as a normally distributed variate with mean 0 and variance 1. The user may choose to adjust the location and/or scale in the driver.


• A qualitative trait can be generated directly as a "marker" locus or indirectly (in the driver), using a quantitative trait as an underlying genetic liability.


• A trait is determined by a list of its components, with the corresponding proportion of the total phenotypic variance attributed to each.


• Traits can share components, enabling models with pleiotropy and other complex situations.
