Unit Test: Genetics TEST NAME: S.7.SCA.2ND.TEST1.1213 TEST ID: 11198 GRADE: Seventh Grade SUBJECT: Life and Physical Sciences TEST CATEGORY: District Benchmark 1. The diagram shows a plant cell. The part of the cell that stores genetic information is — A. V B. X C. Y D. Z 2. One type of genetic material that carries the inherited traits of an organism from parent to offspring is — A. the nervous system B. body cells C. DNA D. skin Unit Test: Genetics 3. Why are the offspring produced by sexual reproduction more diverse than the offspring produced by asexual reproduction? A. The offspring in sexual reproduction inherit genetic material from two parents as opposed to one parent. B. Only sexual reproduction involves cell division. C. Sexual reproduction passes the genetic information to offspring so that it remains unchanged. D. The offspring in sexual reproduction inherit their genetic information from either their male or female parent. 4. Which of the following best describes the purpose of chromosomes? A. To release energy by breaking down food molecules B. To store genetic instructions needed to specify traits C. To store materials inside the cell D. To control what enters and exits the cell 5. Which statement best defines genes? A. A pair of chromosomes in the nucleus B. A section of DNA stored within a chromosome C. The expressed trait of an organism D. The masked allele of an organism Unit Test: Genetics 6. The flatworm in the illustration was accidentally cut into three pieces while swimming among rocks. Each piece will produce a complete worm. As a result, one flatworm will have produced three offspring. What conclusion can you make from these observations? The flatworm produces — A. offspring identical to one another but different from the parent B. offspring that are identical to each other and the parent C. three diverse offspring D. offspring that will not able to reproduce 7. How does sexual reproduction assist adaptation to changing environments? A. Offspring of sexual reproduction have the same genes as each other and their parent. B. The combination of traits from two parents creates uniform offspring. C. Sexual reproduction can be used for regeneration in some organisms. D. The combination of traits from two parents provides opportunity for adaptation. 8. The inherited traits of an individual are contained in its — A. genetic material B. environment C. learned behaviors D. food Unit Test: Genetics 9. Two different species of fish are represented below. Which species of molly reproduces asexually? A. Sailfin mollies reproduce asexually because one parent contributes all of the genetic material resulting in uniform offspring. B. Sailfin mollies reproduce asexually because two parents contribute their genetic material resulting in diverse offspring. C. Amazon mollies reproduce asexually because one parent contributes all of the genetic material resulting in uniform offspring. D. Amazon mollies reproduce asexually because two parents contribute their genetic material resulting in diverse offspring. Unit Test: Genetics 10. In offspring, when a dominant allele (F) and a recessive allele (f) are present, which of the following statements is true? A. The recessive form of the trait will be observed. B. The recessive allele will blend with the dominant allele. C. The recessive form will not be observed but will still be present in the genes. D. The recessive form will not be observed and cannot be passed on to future offspring. 11. When two parents produce an offspring, which of the following statements is true? A. Each parent randomly passes on copies of half of their chromosomes. B. Both parents pass on copies of all of their chromosomes. C. Each parents get to choose which ones and how many chromosomes get passed on. D. Parents don’t pass on any chromosomes. Unit Test: Genetics 12. The structure shown in the picture provided is found in the nucleus of the cell and contains genetic material. What is the structure in the diagram? A. An allele B. An organism C. A gene D. A chromosome 13. What characteristic can be found in the offspring of asexual reproduction? A. Genetic information from more than one parent B. Uniform genetic information C. Diverse appearance D. Alleles from more than one parent 14. What creates diverse offspring? A. Fragmentation B. Sexual reproduction C. Large populations D. Biodiversity Unit Test: Genetics 15. Dominant Recessive Hair Color B = brown b=blonde Eye Color E = brown e = blue Hair texture H = curly h = straight Jocelyn’s phenotype includes curly brown hair and brown eyes. Which set of genotypes could represent Jocelyn’s genotype? A. bb, ee, Hh B. Bb, Ee, hh C. Bb, Ee, HH D. BB, EE, hh
