• Duplication

• Deletion

• Insertion

• Substitution

What is a frameshift mutation?

• A mutation that duplicates a segment of DNA

• A mutation where a base is substituted, but the amino acid remains the same

• A mutation that changes the DNA sequence but not the protein produced

• A mutation that results from the addition or deletion of a base, altering the reading frame

Which chromosomal mutation involves a segment breaking off and attaching to a different chromosome?

• Duplication

• Translocation

• Inversion

• Deletion

What is nondisjunction?

• A type of gene mutation

• A process where chromosomes do not separate completely during meiosis

• A chromosomal duplication event

• A mutation that results in a silent mutation

Why are fruit flies frequently studied in genetics?

• Because they reproduce asexually

• Because they have a large number of chromosomes

• Because they have a short lifespan

• Because their mutations and inheritance patterns are well-documented

What disorder is caused by a mutation in the gene that codes for hemoglobin?

• Down syndrome

• Huntington's disease

• Sickle cell anemia

• Cystic fibrosis

How can carriers of the sickle cell gene mutation have a protective factor against malaria?

• The mutation increases the overall number of red blood cells

• The mutation leads to the production of a different type of hemoglobin that is toxic to the malaria parasite

• The mutation changes the shape of red blood cells, making it harder for the malaria parasite to infect

• The mutation causes an increase in white blood cells

What role do genetic counselors play in the field of genetics?

• They conduct genetic research to discover new mutations

• They study the inheritance patterns in fruit flies

• They help families understand and manage genetic disorders

• They genetically modify organisms for research
