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%
