Concept explainers
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.

- A cell has a diploid number of 6 (2n = 6). a. Draw the cell in metaphase of meiosis I. b. Draw the cell in metaphase of mitosis. c. How many chromosomes are present in a daughter cell after meiosis I? d. How many chromatids are present in a daughter cell after meiosis II? e. How many chromosomes are present in a daughter cell after mitosis? f. How many pairs of homologous chromosomes are visible in the cell in metaphase of meiosis I?arrow_forwardIn the following diagram, designate each daughter cell as diploid (2n) or haploid (n).arrow_forwardFor the animal cell sketch the process of meiosis. Needs to illustrate the process from start to finish, and highlight the chromosomal condition of cells through the meiotic phase Include the labels of: Interphase Mitotic (meiosis I and meiosis II for prophase, metaphase, anaphase, telophase, and cytokinesis)arrow_forward
- 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
- Draw the daugher cells (only the daughter cells, not the process) for each situation below & be sure to include whether the cells are diploid or haploid, number of chromosomes and chromatids for each one. cell has a diploid number of 12 (2n=12) a) daughter cells after mitosis b) daughter cell after meiosis I b) daughter cell after meiosis IIarrow_forwardDiagram metaphase and anaphase of mitosis, meiosis I and meiosis II in a cell containing two different chromosome types (2n=4). Label the spindle fibers, homologous chromosomes, and sister chromatids. Count the total number of chromatids present at each stage.arrow_forwardList down at least 4 differences between Mitosis and Meiosis 2. With a simple sketch, using colored pens provide an illustration (with label) of the cell that will show the comparison of: 1. Anaphase 1 and Anaphase 2 2. Metaphase 1 and Metaphase 2arrow_forward
- Directions: Complete the illustrations that show the differences between mitosis and meiosis. Consider the two-winged fly species Cricotopus sylvestris with chromosome number 2n = 4. Draw the stages (prophase, metaphase, anaphase and telophase with cytokinesis) of the two cell divisions in the corresponding boxes of Table 1. No need to include prometaphase. One box is to one stage. For each stage, draw clearly the appearance and configuration of the cell(s) and the chromosomes. For better illustration, draw the chromosomes with different sizes Use one color for the chromosomes in mitosis and two colors for the chromosomes in meiosis For the description of each stage, include the following: complete name of the stage (include correct number for those that need to have one) unique and important events undergone by the cell(s) and chromosomes appearance and configuration of the chromosomes (thinness or thickness, double-stranded or single-stranded, etc.) number of chromosomes in each…arrow_forwardDirections: Complete the illustrations that show the differences between mitosis and meiosis.

One box is to one stage. For each stage, draw clearly the appearance and configuration of the cell(s) and the chromosomes. Inspect and refer to slides 10 to 11 of the Cell Division PPT for mitosis and slides 14 and 17 for meiosis. Make sure that when the pictures are zoomed in, they will still be clear. For better illustration, draw the chromosomes with different sizes (inspect and refer to slides 10 to 11 of the Cell Division PPT for mitosis and slides 14 and 17 for meiosis). Use one color for the chromosomes in mitosis and two colors for the chromosomes in meiosis (see slides 10 to 11 of the Cell Division PPT for mitosis and…arrow_forwardFor the following events, specify whether they occur during mitosis, meiosis I, or meiosis II:A. Separation of conjoined chromatids within a pair of sisterchromatidsB. Pairing of homologous chromosomesC. Alignment of chromatids along the metaphase plateD. Attachment of sister chromatids to both polesarrow_forward
