ABOUT THIS EPISODE
The effectiveness of any tool depends on whether you’re using it for the right purpose. That’s the story of selection indexes. In this episode, geneticists John Crowley of AbacusBio and Matt Spangler of the University of Nebraska–Lincoln take a hard look at economic indexes, how they’re created and how they’re best used. They tackle criticism and common misconceptions, while exploring how these tools help seedstock and commercial producers make more profitable breeding decisions.
