Which of the following statements best explains what would be different if the diagram showed anaphase I of meiosis instead of anaphase of mitosis? Select one: a. Homologous chromosomes would be moving to the same end of the cell. b. Homologous chromosomes would form a tetrad. c. Each chromosome would have two sister chromatids. d. The sister chromatids would be pulled apart.

Pick an animal of your choice and determine the number of chromatids, chromosomes and tetrads in prophase I. (No humans please, and use google to find the chromosome number of your chosen animal.)

As two students, who will be designated Student J and Student K, were studying together, they argued about the differences between Mitosis and Meiosis (both Meiosis I and Meiosis II). Student J maintained that it if they were looking at very good slides under the microscope and concentrated on Metaphase, it would be possible to tell the difference between the cells undergoing Mitosis, the cells undergoing Meiosis I, and the cells undergoing Meiosis II. Student K said it would be impossible to tell which nuclear division was occurring. Assume there are three unlabeled sets of very good slides of the cells of the common pea plant with one set showing Mitosis, one set showing Meiosis I, and one set showing Meiosis II. To repeat, the slides are unlabeled so the students don’t know which process is occurring in which set. However, the students know that the common pea plant has 14 total chromosomes (or 7 pairs of chromosomes). Explain carefully what Student J would be looking for at the…

Explain mechanisms by which two homologous chromosomes are tied with each other in metaphase I (metaphase in the first meiosis) and by which this tie is lost at the onset of anaphase I (anaphase in the first meiosis). In your answer include an explanation of the mechanism by which sister chromatids are held together during anaphase I.
