Hypothesis
Is there gene flow occurring in nuclear genes between Lutzomyia intermedia and Lutzomyia whitmani?
Conclusion
Introgression might be occurring between L. intermedia and L. whitmani in the period gene, suggesting potential gene flow at other loci as well.
Supporting Evidence
- AMOVA and Fst estimates showed significant differences between species.
- Shared haplotypes were found between L. intermedia and L. whitmani.
- Gene flow tests suggested allele exchange at the per locus.
Takeaway
The study found that two types of sand flies might be mixing their genes, which could affect how they behave and spread diseases.
Methodology
Molecular variation within the period gene was analyzed using sequences from five localities in Eastern Brazil.
Limitations
The study was limited to a specific gene and may not represent broader genetic interactions.
Participant Demographics
Sand flies collected from five localities in Eastern Brazil.
