Exploring Mutations and Pedigrees in Heredity

What type of mutation occurs in body cells and can lead to cancer?

• Germline mutation

• Chromosome mutation

• Point mutation

• Somatic mutation

Which process is responsible for passing on germline mutations to offspring?

• Translation

• Mitosis

• Meiosis

• Transcription

What can be a cause of mutations besides errors in DNA replication?

• UV light exposure

• Blood transfusion

• Physical exercise

• Nutrient deficiency

Which type of mutation involves the change of a single nucleotide?

• Point mutation

• Duplication mutation

• Frameshift mutation

• Non-disjunction

Which disorder is associated with a frameshift mutation?

• Down syndrome

• Sickle cell anemia

• Cystic fibrosis

• Colorblindness

What is a pedigree primarily used for in genetics?

• To identify cellular functions

• To trace inheritance patterns in families

• To classify animal species

• To determine protein structures

What does a shaded symbol in a pedigree typically represent?

• Carrier of a trait

• Presence of a trait

• Mutation in progress

• Lack of a trait

Which genetic disorder is an example of an autosomal recessive condition?

• Klinefelter syndrome

• Cystic fibrosis

• Achondroplasia

• Huntington's disease

How is an autosomal dominant trait inherited?

• Does not skip generations

• Through non-disjunction

• Only from one parent

• Skips generations frequently

Why are males more affected by sex-linked recessive disorders?

• They undergo different mutations

• They inherit two copies of the gene

• They have one X chromosome

• They have two X chromosomes
