Categorisation of environments based on phenotypic variance.

<p>(A) Phenotypic variance of ~1,000 segregants (x-axis) across different environments (y-axis). (B) Phenotypic variance of ~1,000 segregants (y-axis) within each environment (x-axis). Green colour refers to environments with low phenotypic variance (<i>Lv</i>) and pink refers to environments with high phenotypic variance (<i>Hv</i>). The dashed line indicates the median of the distribution. (C) Comparison of phenotypic variance of ~1000 segregants between <i>Hv</i> (y-axis) and <i>Lv</i> (x-axis) environments. A low regression coefficient indicates poor correlation between the two.
