Sesson 1: Analyzing Pedigrees — Practice Questions

  1. 1. A child learns to speak Spanish in school, even though their parents only speak English. The ability to speak Spanish is an example of what kind of trait?

    • A. An inherited trait
    • B. A genetic mutation
    • C. An environmental trait
    • D. A random characteristic
  2. 2. A scientist observes that a mother bear is skilled at catching fish from a river, and her cubs also become skilled at catching fish. Why might this skill NOT be an inherited trait?

    • A. Because the cubs learned the skill by watching their mother.
    • B. Because all bears are naturally born with this skill.
    • C. Because only traits from the father bear can be inherited.
    • D. Because the skill is a random mutation that appeared in the cubs.
  3. 3. A gardener notices that a rose bush planted in sunny soil has bright red flowers, while a similar rose bush planted in a shady spot has pale pink flowers. This difference in flower color is most likely due to the influence of:

    • A. a genetic mutation.
    • B. an inherited trait.
    • C. the environment.
    • D. a random occurrence.
  4. 4. If scientists are studying a family of dogs and notice that most of the puppies have floppy ears just like their parents, what does this pattern suggest?

    • A. Ear shape is determined by the dog's diet.
    • B. Floppy ears are likely an inherited trait.
    • C. The puppies learned to have floppy ears from their parents.
    • D. All dogs in the world must have floppy ears.
  5. 5. Which of the following describes an inherited trait?

    • A. A dog learning to sit on command.
    • B. A child getting a haircut.
    • C. A bird having feathers of a specific natural color passed down from its parents.
    • D. A plant bending towards the sunlight.
  6. 6. Why is it important for scientists to study many families of an organism, instead of just one, when investigating a trait?

    • A. To make the study more expensive and complicated.
    • B. Because it is a rule that all studies must be large.
    • C. To find reliable patterns that appear across different groups.
    • D. To prove that every single offspring is identical to its parent.
  7. 7. When scientists find that a specific trait, like eye color, appears again and again in a family's history, what have they found?

    • A. An opinion
    • B. A pattern
    • C. An accident
    • D. A question
  8. 8. After a scientist collects a large amount of information on the fur color of mice and their parents, what is the next logical step in their investigation?

    • A. End the experiment.
    • B. Look for patterns.
    • C. Form a question.
    • D. Get new mice.
  9. 9. In a scientific study about animal traits, what does the term 'data' refer to?

    • A. The scientist's opinion about the animals.
    • B. Information collected about parents and their offspring.
    • C. The equipment used to observe the animals.
    • D. A final guess about which traits are inherited.
  10. 10. A botanist observes that in a large field, tall pea plants almost always produce tall offspring, and this happens generation after generation. What has the botanist identified?

    • A. An experimental error.
    • B. A pattern suggesting the trait is inherited.
    • C. A random event that is unlikely to repeat.
    • D. A trait caused only by the environment.
