  2. Base pairs (bp)
  3. Micrometers (μm)
  4. Nanometers (nm)
Question 5 Multiple Choice (Single Answer)

What is the relationship between genetic distance and physical distance?

  1. Genetic distance is always proportional to physical distance
  2. Genetic distance is always inversely proportional to physical distance
  3. Genetic distance and physical distance are not related
  4. The relationship between genetic distance and physical distance depends on the genetic markers being used
Question 6 Multiple Choice (Single Answer)

What is a genetic map used for?

  1. To identify the location of genes on a chromosome

Question 7 Multiple Choice (Single Answer)

What is the difference between a genetic map and a physical map?

  1. A genetic map shows the relative positions of genes on a chromosome, while a physical map shows the actual sequence of nucleotides in a chromosome
