Hypothesis
Does the involvement of the same genomic loci in convergent phenotypes suggest that developmental constraints give rise to shared phenotypes?
Conclusion
A single conserved locus is responsible for producing wing pattern diversity in Heliconius butterflies.
Supporting Evidence
- The study found that the same genomic loci are involved in color pattern variation across different butterfly species.
- The researchers identified major color-patterning loci in individual offspring from different subspecies.
- The results suggest that the conserved locus provides flexibility for natural selection in producing diverse wing patterns.
Takeaway
Scientists found that a special group of genes helps butterflies have different wing patterns, which helps them survive by mimicking other species.
Methodology
The researchers crossed different races of three species of Heliconius butterflies and genotyped the offspring to identify genes responsible for color patterns.
