Treyvon constructed a pedigree for three generations of his family. He learned that his

heart attacks, obesity). What does this predict for Treyvon? - Answers - He has an
increased risk of developing a heart-related disease
BRCA mutation like what Emma Duncan had - Answers - Autosomal dominant
Match the disorder we discussed in class with the inheritance pattern - Answers -
Huntington's Disease: Autosomal dominant
Dwarfism: autosomal dominant
sickle cell anemia: autosomal recessive
color blindness: sex linked
hemophilia: sex linked
cystic fibrosis: autosomal recessive
hemmingways cat toes: variable expressivity
brittle bone disease: incomplete dominance
