Hypothesis
What are the specific genes that control the mimetic wing patterns of Heliconius erato and Heliconius melpomene?
Conclusion
The study shows that fine-scale gene order is highly conserved between distantly related Heliconius species and also between Heliconius and Bombyx mori.
Supporting Evidence
- Markers linked to color pattern genes were identified using AFLP polymorphisms.
- High levels of sequence conservation were found between Heliconius species.
- Novel repetitive elements were discovered in the Heliconius genome.
Takeaway
Scientists studied butterflies to find out which genes control their colorful wing patterns, and they discovered that these genes are very similar across different butterfly species.
Methodology
The study used AFLP polymorphisms to identify markers linked to color pattern genes and sequenced BAC clones containing these genes.
Limitations
The study primarily focused on two color pattern loci and may not represent the entire genomic landscape of Heliconius butterflies.
