Does male gonopodial morphology affect male-female mating positioning in the livebearing fish Xenophallus umbratilis?

Laterality Index (LI) scores from the Multiple Male assay for the sinistral (upper bar) and dextral (lower bar) treatments.
Each test was comprised of one female and five same-morph males, all from the same population. Positive LI scores indicate positioning bias on the right of a female and negative LI scores indicat positioning bias on the left side of a female. A more detailed definition of the LI can be found in the Methods. Figure shows a bar chart with error bars depicting ±2 SE. Dots represent LI scores for each individual in this assay.
