Which mode of inheritance is characterized by each affected person having an affected parent and occurs in every generation?

• Autosomal Dominant

• X-linked Recessive

• Autosomal Recessive

• X-linked Dominant

In which mode of inheritance are both parents of an affected person carriers, but the disease is not typically seen in every generation?

• Autosomal Recessive

• X-linked Recessive

• Autosomal Dominant

• Mitochondrial

Which mode of inheritance affects males more frequently and often presents affected males in each generation?

• X-linked Recessive

• Mitochondrial

• X-linked Dominant

• Autosomal Recessive

In which mode of inheritance can both males and females be affected, but the disease is only passed on by females?

• Autosomal Recessive

• Mitochondrial

• Autosomal Dominant

• X-linked Dominant

What is nondisjunction?

• A type of genetic mutation

• Chromatids or homologs not separating during meiosis

• A method of genetic recombination
