Chapter 13, Problem 6TYU
DRAW IT The diagram shows a cell in meiosis.
(a) Label the appropriate structures with these terms: chromosome (label as duplicated or unduplicated), centromere, 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 H genes.
(b) Describe the makeup of a haploid set and a diploid set.
(c) Identify the stage of meiosis shown.

Draw a side-by-side comparison of mitosis and meiosis. Include 6 chromosomes in your drawings at the beginning of mitosis and meiosis. Be sure to label the following in each of your drawings where appropriate: chromosomes/chromatin/sister chromatids, mitotic spindle, asters, centromeres, microtubules, centrosomes, kinetochore, and nuclear membrane.
Construct a table similar to that in Figure 2.12 for the different stages of meiosis, giving the number of chromosomes per cell and the number of DNA molecules per cell for a cell that begins with 4 chromosomes (two homologous pairs) in G1. Include the following stages in your table: G1, S, G2, prophase I, metaphase I, anaphase I, telophase I (after cytokinesis), prophase II, metaphase II, anaphase II, and telophase II (after cytokinesis).
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.

- Fill in the blanks. The parentheses represent choices for each blank. In both mitosis and ________ (meiosis I, meiosis II) , a spindle forms and separates sister chromatids. While mitosis produces two nuclei, meiosis II produces _________ (four haploid nuclei, two haploid nuclei).arrow_forwardThe following four questions refer to the picture below: 1) In meiosis, the homologous chromosomes are side by side. Are they side by side in mitosis? 2)In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides? 3) Look at what happened right after Metaphase in both processes. In mitosis, what has been separated homologous chromosomes or sister chromatids? 4) After Metaphase I in meiosis, what has been separated, homologous chromosomes or sister chromatids?arrow_forwardWhich is more similar to anaphase of mitosis, anaphase 1 or anaphase 2 of meiosis? Why? Group of answer choices 1. anaphase 1 because sister chromatids are being separated 2. anaphase 2 because homologous chromosomes are being separated 3. anaphase 2 because sister chromatids are being separated 4. anaphase 1 because homologous chromosomes are being separatedarrow_forward
