This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).
This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.
This video describes the technology of metabarcoding, which allows scientists to determine herbivore diets based on the sequences of plant DNA extracted from animal dung.
A number of questions are embedded within the short film Popped Secret: The Mysterious Origin of Corn, which explores the genetic and archaeological evidence that corn was domesticated from a wild Mexican grass called teosinte.
This film explores the genetic and archaeological evidence that suggest that corn is the result of the domestication of a wild Mexican grass called teosinte.
