Narrator: This is Science Today. The University of California , Davis Veterinary Genetics Laboratory leads the world in DNA parentage testing for horse registries. Lab director Cecilia Penedo says in addition to their genotyping service for animal identification, they also do diagnostic tests for genetic diseases in horses.
Penedo: Genetic diseases may cause a loss of breedings, if one produces an affected foal. And therefore, it is important in many cases to screen the breeding stock before breeding decisions are made.
Narrator: The UC Davis lab has been doing genotyping for 40 years – that's longer than anyone else.
Penedo: As a non-profit lab associated with a university, the income from our genotyping service goes back to the laboratory and the university to support research programs, to support additional developments that will improve our service.
Narrator: For Science Today, Larissa Branin.
