  3. C. Cell

  4. One pair of genes that determine a specific trait. A. Chromosomes B. DNA molecules C.ChromatidsD. Alleles

  5. D. Alleles

  6. A ________ can be defined as a basic unit of hereditary information which refers to a specific segment of DNA that influences a particular trait or group of traits. A. chromosome B. genome C. gene D. zygote

  7. C. Gene

  8. Which of the following is true about genes? A. Genes are made up of smaller molecules known as chromosomes. B. Genes are responsible for all the traits of an organism. C. The genes of a particular organism can never change throughout its lifetime. D. In humans, genes are passed to an offspring from two parents.

  9. D. In humans, genes are passed to an offspring from two parents.

  10. Within your cells, the genetic material that controls your traits is located in an organelle called... A. the mitochondrion. B. the chloroplast. C. the nucleus. D. the ribosome.

  11. B. Nucleus

  12. B = Brown; b = blueBB x bbProvide the % of each genotype/phenotype

  13. 100% Bb (Brown)

  14. DAILY DOUBLESickle-cell anemia is a genetic disorder of the blood in which the shape of red blood cells is distorted, resulting in a variety of health problems. The allele for normal blood cell production (H) is dominant to the allele for sickle cell production (h). If one parent has sickle-cell anemia and the other parent is a carrier, what is the probability that their child will have sickle-cell anemia?Parents: Hh x hh Daily double

  15. 50% hh (sickle cell anemia)50% Hh (carrier)

  16. In humans, the allele for brown eyes (B) is dominant to the allele for blue eyes (b). What is the probability that two heterozygous brown-eyed parents will have a child with blue eyes? A. 50% B. 0% C. 75% D. 25%

  17. D. 25%

  18. In a particular type of cat, coat color follows the dominant/recessive pattern of inheritance. The allele for a brown coat (B) is dominant to the allele for a white coat (b).A cross between two white-coated cats would result in... A. white-coated kittens or brown-coated kittens. B. white-coated kittens only. C. brown-coated kittens only. D. white-coated kittens with brown spots.

  19. B. White Kittens only

  20. In fruit flies, the allele for white eyes (W) is dominant to the allele for red eyes (w). Two heterozygous fruit flies are crossed, resulting in many offspring. Which of the following would best describe the population of offspring? A. All of the offspring population is white-eyed. B. The majority of the offspring population is white-eyed. C. The majority of the offspring population is red-eyed. D. About half of the offspring population is red-eyed, and the other half of the population is white-eyed.

  21. B. The majority of the offspring population will be white eyed.

  22. An organism that contains two of the same alleles for a trait is said to be __________ for that trait. A. recessive B. heterozygous C. homozygous D. dominant

  23. C. Homozygous

  24. An organism that contains two different alleles for a trait is said to be __________ for that trait. A. recessive B. heterozygous C. homozygous D. dominant

  25. B. heterozygous

  26. If a Homozygous Brown (B) fur cat and a Heterozygous Brown fur cat have offspring, what is the probability the kittens will have homozygous brown fur?A. 25% C. 75%B. 50% D. 100%

  27. B. 50%

  28. Huntington's disease is a genetic disorder that can result in memory loss and abnormal body movements. Huntington's disease results from a defective gene (H) that is dominant to the allele that produces normal function (h). This means that...I.if someone is heterozygous for Huntington's disease, then he/she will be a carrier but will not have the disease.II.if a child has Huntington's disease, then at least one of his/her parents has the disease. III.if two parents do not have Huntington's disease, then their children will not have the disease.A. I, II, and III B. II and III only C. II only D. I and II only

  29. B. II and III only

  30. Would these parents have heterozygous or homozygous offspring?TT x tt

  31. Heterozygous Tt

  32. The instructions, or code, that is responsible for all the inherited traits of an organism... A. is formed after an organism is fully-grown. B. is held in genetic material called DNA. C. is stored within the mitochondria of cells. D. is passed from the offspring to the parent.

  33. B. Is held in genetic material called DNA

  34. A molecule of DNA is "packaged" and carried by a larger molecule called a __________. A. vacuole B. chromosome C. gamete D. diploid

  35. B. chromosome

  36. Which of the following are true?I.A single gene can control a single trait.II.A single gene can influence multiple traits.III.A single trait can be controlled by multiple genes.A. I and II only B. II and III only C. I and III only D. I, II, and III

  37. D. I, II, and III

  38. A widow's peak is a V-shaped area of the hairline in the center of the forehead. The allele for having a widow's peak is dominant to the allele for not having a widow's peak. If two parents do not have widow's peaks, what is the probability that their child will have a widow's peak? A. 75% B. 0% C. 50% D. 25% (Daily Double)

  39. B. 0% Daily Double!!!

  40. Many human diseases follow the dominant/recessive pattern of inheritance. If an individual possesses an allele for a disease, but does not have the disease, this person is known as a ___________. A. mutant B. genotype C. carrier D. messenger

  41. C. Carrier
