BIO 340 EXAM 1 STUDY GUIDE QUESTIONS AND ANSWERS WITH SOLUTIONS 2024 Mitosis and Meiosis II - ANSWER In which nuclear division process do sister chromatids segregate? chiasmata - ANSWER At metaphase I, homologous chromosomes are connected only at what structure? Pairing of homologous chromosomes - ANSWER Which of the following is unique to prophase I of meiosis? 16 - ANSWER If a muscle cell of a typical organism has 32 chromosome, how many chromosomes will be in a gamete of that same organism? four haploid - ANSWER Meiosis produces ___________ daughter cells All offspring with red eyes - ANSWER In a cross between a homozygous red -eyed female fruit fly and a white -eyed male fruit fly, what is the expected outcome? All male offspring with white eyes - ANSWER In a cross between a white -eyed female fruit fly and a red -eyed male fruit fly, what is the expected outcome? 50% - ANSWER Hemophilia is an x -linked recessive pattern. A carrier woman (one affected X chromosome) married a man with hemophilia and they have children. What percent of their boy children will be affected?

What inheritance pattern would this be indicative of? Codominance - ANSWER A person with only one Sickle Cell Anemia allele and one unaffected allele will have some normal red blood cells and some abnormal. What inheritance pattern would this be indicative of? DNA - ANSWER In Griffith's experiments, what made the harmless R cells grow capsules when exposed to heat -killed S cells? Be incorporated into the phage protein coat because some amino acids contain sulfur - ANSWER In the Hershey -Chase experiment radioactive Sulfur was used to: Radioactive phosphorus was found inside the cell - ANSWER The experiments by Hershey and Chase helped confirm that DNA was the hereditary material on the basis of the finding that: 23 percent - ANSWER If DNA of a particular species was analyzed and it was found that it contains 27 percent of adenine (A), what would be the percentage of cytosine (C)?
