- Select 5 correct answer(s) Question 5 options: A) In fruit flies, sex is determined by the ratio of the number of X chromosomes to sets of autosomes.. B) In mammals, sex is determined by a single gene on the X chromosome. C) Sister chromatids are held together by unreplicated centromeres. D) Crossovers, in combination with sister chromatid cohesion, physically connect homologs at metaphase of meiosis I. E) Homologous chromosomes have identical DNA sequences. F) In mammals, sex is determined by a single gene on the Y chromosome. G) At mitosis, microtubules attach to kinetochores located at telomeres to segregate sister chromatids to opposite poles. H) Chromosomes that fail to have at least one crossover have an increased risk of meiosis I…Task: Show your work/explain your reasoning as much as possible Grading Criteria: I want the correct answer and I want to see your work or read an explanation of your reasoning.

The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. b.) The daughter cells produced in mitosis are genetically similar to the parent cells and have the same number of chromosomes, while these are genetically different in meiosis and have half the number of chromosomes. c.) The daughter cells produced in both cases are genetically similar to the parent cells, but in meiosis, there are fewer chromosomes. d.) The daughter cells produced in both cases are genetically different, but in mitosis, there are fewwer chromosomes in daughter cells. 2.)
