  1. Saving the California Condor Amy Welsh Jed Doelling Emily Lilly Sarah Josway Randy Phyllis Stephanie Young

  2. 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

  3. California Condors • Critically endangered • 22 individuals • Captive breeding program • Some mating pairs frequently produced non-hatching eggs • Chondrodystrophy • Lethal disorder

  4. Genetics Review for Pedigree Analysis A Amut A AA AAmut AmutAmutAAmutAmut Gamete from mother Gamete from father

  5. Pedigree Analysis Female Affected female Male Affected male

  6. A C B Female Affected female Male Affected male Dead affected male / Is this trait inherited as 1) Dominant 2) Recessive http://highered.mcgraw-hill.com/

  7. A C B Female Affected female Male Affected male Dead affected male / What is the genotype of individual A 1) Homozygous dominant 2) Homozygous recessive 3) Heterozygous 4) Too little information http://highered.mcgraw-hill.com/

  8. 1 3 2 4 Female Affected female Male Affected male Dead affected male / Which individual is LEAST likely to carry the mutant allele? http://highered.mcgraw-hill.com/
