Project to Obtain Butterfly DNA through Wing Swabs Wraps Up

Our Department of Defense Legacy Program Grant (Project 12-608) to develop a technique to sample DNA from live butterflies has wrapped up. The project was a collaboration with Dr. Jana Johnson at Moorpark College, Dr. Bob Wayne’s lab at UCLA, and a couple of groups working with endangered butterflies around the country. The objective of … Continue reading Project to Obtain Butterfly DNA through Wing Swabs Wraps Up
