Hypothesis
Is there a correlation between male red coloration and female visual sensitivity in sticklebacks?
Conclusion
The study found that male sticklebacks' red coloration is associated with their daughters' sensitivity to red wavelengths.
Supporting Evidence
- The red color expression of fathers correlates well with their daughters' red sensitivity.
- Variation in female red sensitivity may influence mating preferences.
- The study supports the sensory drive hypothesis in sexual selection.
Takeaway
Male sticklebacks that are redder are more likely to have daughters who can see red better.
Methodology
The study measured male coloration and female visual sensitivity using spectrophotometry and optomotor response tests.
Limitations
The study did not address the direct association between visual perception and mating preferences.
Participant Demographics
Threespine sticklebacks from an anadromous, genetically heterogeneous population.
