Observe the diagram below and answer the following questions: Homologous Chromosomes 1. Which process is represented in these diagrams? Mitosis or meiosis? Explain your answer. 2. How many chromosomes did the cell start with? 3. How many chromosomes are present at the end of division I? 4. How many chromosomes are present in each cell at the end of division II? 5. Explain how meiosis results in UNIQUE cells. 6. Is this cell division occurring in a plant cell or an animal cell? What is the main difference between the two divisions?

Step 1
- To determine whether the process is mitosis or meiosis, observe the number of divisions and the chromosome behavior. Mitosis involves one division resulting in two identical cells, while meiosis involves two divisions resulting in four genetically unique Show moreā¦

Mitosis vs. Meiosis Questions: 1. Number of cells before division? 2. Is the parent cell haploid or diploid? 3. Number of cells after division? 4. Are the daughter cells haploid or diploid? 5. Are the daughter cells identical to the parent cell? 6. In humans, the number of chromosomes before division? 7. In humans, the number of chromosomes after division? 8. How many cell divisions occur? 9. In what type of cells does the division occur? (somatic or gamete) 10. Does crossing over occur? 11. Number of sets of chromosomes in daughter cells? 12. What is the purpose of this type of cell division? 13. What are the stages of this cell division?

Draw a diagram that shows the arrangement of chromosomes during the following stages of meiosis: 1. An animal cell (2n=8) at metaphase I 2. A plant cell (2n=4) at anaphase II 3. A plant cell (2n=8) at telophase I 4. An animal cell (2n=6) at telophase II 5. A plant cell (2n=8) at prophase II

DRAW IT The diagram shows a cell in meiosis. (a) Label the appropriate structures with these terms: chromosome (label as duplicated or unduplicated $, \mathrm{cen}-$ tromere, kinetochore, sister chromatids, nonsister chromatids, homologous pair (use a bracket when labeling $)$ homolog (label each one), chiasma, sister chromatid cohesion, and gene loci, labeling the alleles of the F and $\mathrm{H}$ genes. (b) Describe the makeup of a haploid set and a diploid set. (c) Identify the stage of meiosis shown.
