Hypothesis
How do the mutations Missing and Spotty affect the eyespot patterns on butterfly wings?
Conclusion
The mutation Missing reduces the size of specific eyespots on both forewings and hindwings, while Spotty introduces additional eyespots only on the forewings.
Supporting Evidence
- The Missing mutation reduces the size of two hindwing eyespots.
- Spotty introduces two extra eyespots on the forewing.
- The combined effect of Missing and Spotty shows an interaction on forewing eyespots.
Takeaway
Some butterflies have special genes that change the patterns on their wings. One gene makes some spots smaller, and another gene can add new spots.
Methodology
The study involved crossing butterflies with different mutations and measuring the size of their eyespots.
Potential Biases
Potential bias in selecting extreme phenotypes for analysis.
Limitations
The study may not account for all genetic factors influencing eyespot size and differentiation.
Participant Demographics
Nymphalid butterfly, Bicyclus anynana.
