Hypothesis
What is the role of gene flow in the origin of Heliconius heurippa?
Conclusion
The origin of Heliconius heurippa may have involved limited introgression of color pattern genes from H. melpomene into the H. cydno genome.
Supporting Evidence
- H. heurippa shows a shared distribution of alleles from both parental lineages.
- Ongoing introgression is frequent between H. heurippa, H. cydno, and H. melpomene.
- Behavioral experiments indicate that the hybrid color pattern is critical for mate recognition.
Takeaway
Heliconius heurippa is a butterfly that likely formed through mixing genes from two other butterflies, H. cydno and H. melpomene, which helps it survive better.
Methodology
Phylogenetic and coalescent-based analyses of multilocus sequence data were used to study the genetic relationships.
Potential Biases
Potential biases may arise from the selection of loci that do not represent the entire genome.
Limitations
The study may not fully capture the complexity of hybrid speciation due to the limited number of loci analyzed.
Participant Demographics
Butterflies collected from Colombia and Venezuela.
