Formative #3 for 4/5

Which of Mendel's laws states that the alleles for one trait do not affect another?

• Law of segregation
• Law of independent assortment
• Law of dominance
• Law of genetic linkage

In order for an offspring to show both recessive traits, what does the genotype look like?

• heterozygous

  GgKk

• homozygous recessive

  ggkk

• homozygous dominant

  GGKK

• not possible

Why can humans have offspring that are brown hair and blue eyes or brown hair and brown eyes?

• Th law of independent assortment tells us that the traits do not affect each other.

• Humans can only have offspring with the same hair and eye color as their parents.
• Eye color is determined solely by environmental factors, not genetics.
• Brown hair and blue eyes are a result of a single gene mutation.

Which of the following is a beneficial impact of GMO crops?

• Increased agricultural productivity and pest resistance.
• Decreased crop yields and increased pesticide use.
• Higher costs for farmers and reduced food quality.
• Increased soil erosion and loss of biodiversity.

Transgenesis is the movement of genetic information from one organism to another. Which of the following is a drawback of doing this?

• Enhanced resistance to pests and diseases.
• Increased crop yield and food security.
• Potential ecological disruption and health risks.
• Improved nutritional content of food.

Why would scientists use bacteria to produce insulin?

• Bacteria can be genetically engineered to produce human insulin efficiently and cost-effectively.
• Bacteria are not capable of producing any proteins.
• Insulin production in bacteria is too slow for medical use.
• Bacteria can only produce animal insulin.
