Hypothesis
What is the level of nucleotide diversity in the willow grouse compared to other bird species?
Conclusion
The study found unusually high levels of nucleotide diversity in the Scandinavian willow grouse with very little population structure among localities.
Supporting Evidence
- Total nucleotide diversity was found to be between 1.30 × 10-4 and 7.66 × 10-3.
- The synonymous nucleotide diversity was approximately 20 times higher than in humans.
- FST values revealed low levels of differentiation among the four localities.
- Linkage disequilibrium was low, indicating a large outbred population.
Takeaway
The willow grouse has a lot of genetic variety, which means it's a healthy population, and they don't differ much from one place to another.
Methodology
The study sequenced 18 autosomal protein coding loci from 64 individuals across four populations in Scandinavia.
Participant Demographics
64 willow grouse from four locations in Scandinavia.
