- 18th century
- Mid-19th century
- Early 20th century
- Late 19th century
A: Mid-19th century

Q: How does the Law of Segregation explain the inheritance of traits?
- Traits are inherited independently of one another.
- Alleles for a trait separate during gamete formation.
- All traits are dominant.
- Only recessive traits are passed on.
A: Alleles for a trait separate during gamete formation.

Q: Which of the following best describes the structure of DNA?
- A single strand of nucleotides
- A double helix composed of amino acids
- Two strands of nucleotides twisted together
- A linear chain of proteins
A: Two strands of nucleotides twisted together

Q: Why is gene regulation important in living organisms?
- It ensures that all genes are expressed simultaneously.
- It allows for proper cellular function and environmental response.
- It prevents mutations from occurring.
- It guarantees the inheritance of dominant traits.
A: It allows for proper cellular function and environmental response.

Q: How does a Punnett square assist in genetic predictions?
- It shows the physical appearance of organisms.
- It predicts the probability of offspring inheriting specific traits.
- It determines the age of organisms.
- It illustrates the structure of DNA.
A: It predicts the probability of offspring inheriting specific traits.

Q: Which statement best connects epigenetics to environmental factors?
- Epigenetics involves changes to the DNA sequence.
- Environmental factors have no impact on gene expression.
- Epigenetics studies changes in gene expression without altering DNA.
- All genetic traits are fixed and unchangeable.
A: Epigenetics studies changes in gene expression without altering DNA.

Q: What is the primary function of messenger RNA (mRNA) in gene expression?
- To replicate DNA
- To transport amino acids
- To serve as a template for protein synthesis
- To regulate gene expression
A: To serve as a template for protein synthesis

Q: How might advancements in genetic technologies like CRISPR-Cas9 impact society?
- They will eliminate all genetic disorders.
- They will allow for precise editing of DNA, influencing research and applications.
- They will make genetic research unnecessary.
- They will only benefit agricultural practices.
A: They will allow for precise editing of DNA, influencing research and applications.
