Diversity of interference characteristics. Parameter nu of the Gamma model measuring interference intensity in pathway P1 (x-axis), versus fraction p of crossovers formed via the non-interfering pathway P2 (y-axis). (A) Parameters estimated for each population and the 10 chromosomes pooled together. Red circles: Dent × Dent populations. Blue triangles: Flint × Flint populations. Corresponding population names are indicated beside each point. Pooled data for the two pools Dent and Flint are indicated with their 95% confidence intervals (error bars). (B) Parameters for the pooled data of all Dent × Dent populations (red circles) and all Flint × Flint populations (blue triangles) estimated for each individual chromosome. Corresponding chromosome numbers are indicated beside each point.
