Natural genetic variation in Drosophila R8 photoreceptors spans eight qualitatively distinct Rh5/Rh6 expression phenotypes, including Rh5/Rh6 co-expression and loss of detectable expression.
- Why it matters: Complex traits are hard to map genetically, but endophenotypes can expose how genotype variation shapes intermediate neuronal identity states.
- What they did: The study used Rh5 and Rh6 expression in Drosophila R8s to infer subtype identity, applying simple expression rules to predict eight phenotypes and testing field flies and wild-derived inbred lines.
- The result: Deviations matching all eight predicted phenotypes were observed, and causal coding and regulatory variants in sevenless, Rh5, Rh6, and melted were linked to different levels of the developmental program.
