'Ghost Genes' Could Help Save The American Red Wolf
Oct 22, 2024
In this engaging discussion, Bridget Von Holt, a professor at Princeton specializing in red wolf genetics, reveals the fascinating challenge of reviving the American red wolf, descended from just 14 canids. She introduces the revolutionary concept of 'ghost genes' to enhance genetic diversity by tapping into coyote genetics. The conversation dives into the importance of careful breeding to avoid inbreeding and the significant role of conservation efforts since the species was nearly extinct in the 1970s. Discover how science is crafting a hopeful future for this critically endangered animal!

Episode notes
A Photo That Changed Everything
- In 2016, community scientist Ron Wooten sent Bridget VonHoldt a photo of a coyote.
- This photo sparked a research project on red wolf genetics.
Ghost Wolves
- Coyotes with red wolf DNA are called "ghost wolves."
- The goal is to bring this "ghost DNA" to the surface and accumulate it in a few individuals.
Genetic Dictionary
- Bridget VonHoldt created a genetic "dictionary" of wolves, dogs, and coyotes.
- This dictionary helps identify red wolf DNA that wasn't part of the original captive breeding program.
