Amy WelshJed DoellingEmily LillySarah JoswayRandy PhyllisStephanie 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 o Chondrodystrophy
Lethal disorder

California Condors: Success Story
• As of March 2011, total population is 369 birds
• Frequency of lethal allele is down to 8.8% from 20%
