Saving the California Condor Amy Welsh Jed Doelling Emily Lilly Sarah Josway Randy Phyllis Stephanie Young
Goals • Apply Mendelian genetics and pedigree analysis to modern problems • Outcomes • Use information from pedigree analysis to design optimal breeding pairs for the California Condor
California Condors • Critically endangered • 22 individuals • Captive breeding program • Some mating pairs frequently produced non-hatching eggs • Chondrodystrophy • Lethal disorder
