Inheritance and Genetics

1. Inheritance and Genetics Quiz

2. 1. Both parents of a Siamese cat have green eyes. Their offspring also have green eyes. This would be an example of: • An acquired trait • An inherited trait • A learned trait • A recessive trait

3. 2. You are given three unknown organisms labeled A, B, C. When looking at the DNA of the three unknown organisms, you find that they all have the exact same sequence of DNA. Which statement below is the most logical explanation? • A,B and C were reproduced asexually from a common parent • A,B and C were reproduced sexually from the same parents • A and B are the parents of C • A, B and C are unrelated

4. 3. You are given three unknown organisms labeled A, B, C. When looking at the DNA of the three unknown organisms, you find that the DNA of organism C is a combination of the DNA from A and B. Which statement below is the most logical explanation? • A,B and C were reproduced asexually from a common parent • A,B and C were reproduced sexually from the same parents • A and B are the parents of C • A, B and C are unrelated

5. 4. Liz has beautiful auburn hair and hazel eyes, just like her Aunt Ann. Liz probably got these traits from her aunt. Which of the following accurately describes this statement? • True, hair and eye color are inherited. • False, hair and eye color are acquired. • True, traits sometimes skip a generation. • False, Liz can only inherit traits from her parents.

6. 5. If the gene code for protein in a bacteria cell read: CTTAGCTAG, what would be the code for that protein in the offspring’s cell? • GAATCGATC • CTTAGCTAG • It cannot be determined • It depends on the genetic code of the other parent.

7. 6. Jeff’s dad is a great hunter. People keep telling Jeff that he will also be a good hunter one day because he will “get it from his dad.” What kind of assumption are people making when they say this? • Stating evidence – hunting is an inherited trait • Stating evidence – hunting ability is an acquired trait • Inference – hunting ability is an inherited trait • Inference – hunting ability is an acquired trait

8. 7. Whom of the following would most benefit from the study of genetics? • musician • accountant • dairy farmer • construction worker

9. 8. Your mother sends you to the store to buy tomatoes. You notice that there are several choices, and one sign advertises, “genetically engineered to stay firmer longer with more sweetness.” How could you test these claims? • Ask you neighbor who is a farmer if these claims are true. • Buy 2 genetically engineered tomatoes and compare them. • Buy a genetically engineered tomato and a regular tomato and compare the two. • It is not possible for a student to do this test.

10. 9. One of the traits of a tulip is that its petals open in response to sunlight. What type of trait is this? • Inherited trait because it describes something the tulip plant DOES. • Inherited trait because this behavior is coded in the DNA of the tulip plant. • Acquired trait because the parent tulip plants acted the same way. • Cannot be determined with this information.

11. 10. Which of the following is an INFERENCE about asexual reproduction. • Aspen trees can reproduce asexually. • Grafting is a man-made form of asexual reproduction. • Asexual reproduction transfers 100% of the genetic code from parent to offspring. • Asexual reproduction is better than sexual reproduction.
