University of Maryland, Baltimore SCI 2162 BIO Quiz - Heredity Question 1 Points: 10 out of 10 Genotypes provide information about A DNA B Proteins C Carbohydrates D Lipids Question 2 Poi... nts: 0 out of 10 List all possible gametes that can be produced from a cell that has the following genotype: AaBBDd. A A, a, B, D, d B ABD, abd C ABD, ABd, AbD, Abd, aBD, aBd, abD, abd D ABD, ABd, aBD, aBd Question 3 Points: 10 out of 10 Which of the following is true of a diploid organism? A It has two of each gene. B It has two of each chromosome. C It has two alleles of each gene. D All of the above. E None of the above. Question 4 Points: 10 out of 10 Homologous pairs of chromosomes line up at the center of the cell in during which stage of meiosis? A Metaphase I B Metaphase II C Telophase I D Telophase II Question 5 Points: 10 out of 10 Crossing over occurs: _______________. A during mitosis but not meiosis B during both meiosis I and meiosis II C during meiosis I only D during meiosis II only Question 6 Points: 10 out of 10 The sister chromatids separate during which stage of meiosis? A Anaphase I B Anaphase II C Prophase I D Prophase II Question 7 Points: 10 out of 10 Describe the importance of independent assortment: ________________________. A will assort independently of each other B will sort to the same gamete C are called alleles D All of these are true Question 8 Points: 10 out of 10 The next three questions are based on the following information. In humans, the ability to roll the tongue (T) is dominant over the inability to do so (t). Suppose Mike, who can roll his tongue, and Jeannie, who cannot roll her tongue, have a child, Benjamin. Part 1 of 3: If Mike’s mother was able to roll her tongue but his father was not able to roll his, then what is the probability that Benjamin will be able to roll his tongue? A 0% B 75% C 50% D 100% Question 9 Points: 10 out of 10 Part 2 of 3: What is the probability that Benjamin will be homozygous recessive? A 75% B 50% C 100% D 0% Question 10 Points: 0 out of 10 Part 3 of 3: What is the probability that Benjamin will be homozygous dominant? A 50% B 75% C 0% D 100% Question 11 Points: 10 out of 10 Which relationship is correct? A Protein is to phenotype as genotype is to DNA. B Protein is to genotype as DNA is to phenotype. C Protein is to phenotype as DNA is to genotype. D Phenotype is to protein as DNA is to genotype. Question 12 Points: 10 out of 10 Which of these discusses genotypes rather than phenotypes. A The offspring of these flowers can be either red or white. B The male mouse is homozygous dominant. C Lactose intolerance can be due to a missing protein (the enzyme that digests lactose). D All of these discuss genotypes [Show More]
