publication Evidence: moderate

Author Information

Author(s): Petko M. Petkov, Joel H. Graber, Gary A Churchill, Keith DiPetrillo, Benjamin L. King, Kenneth Paigen

Primary Institution: The Jackson Laboratory

Hypothesis

The mammalian genome contains blocks of functionally related genes.

Conclusion

The recalculated results provide additional support for the original conclusions regarding the functional organization of mammalian genomes.

Supporting Evidence

  • The recalculated genetic map length is 14.7% shorter than previous estimates.
  • Communication with the authors of the challenged study confirmed the new results.

Takeaway

Scientists found that genes in mammals are organized in blocks that work together, and new calculations support this idea.

Methodology

Revised calculations of genetic distances using a specific methodology.

Limitations

The initial findings were challenged due to inappropriate data inclusion in the analysis.

Participant Demographics

Authors are affiliated with The Jackson Laboratory and Novartis.
