Textbook Question
Chapter 2, Problem 2PDQ
Review the Chapter Concepts list on page 14. All of these pertain to conceptual issues involving mitosis or meiosis. Based on these concepts, write a short essay that contrasts mitosis and meiosis, including their respective roles in organisms, the mechanisms by which they achieve their respective outcomes, and the consequences should either process foil to be executed with absolute fidelity.

This is a three part question:
Mitosis and meiosis are both processes of eukaryotic cell division, with the same names used to describe different stags.
a. What are the significant cellular and chromosomal events that occur during each stage of mitosis?
b. What are the similarities and differences between the events that occur during each stage of mitosis and the corresponding stage of meiosis I?
c. What are the similarities and differences between the events that occur during each stage of mitosis and the corresponding stage of meiosis II?
Please explain (and simply) the process of mitosis and meiosis. What are the differences between them?
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…

- Provide two reasons why meiosis leads to genetic variation in diploid organisms.arrow_forwardDirections: 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. 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).

The first meiotic division in the hybrid animal shows a mixture of paired and single chromosomes. Why do you suppose this occurs? Can you suggest a possible relationship between the mixed chromosomes and the observed sterility of the hybrid?arrow_forward
- Define and discuss these terms: sister chromatidsarrow_forwardUse the following information as the basis for answering the question: A diploid eukaryotic organism has 4 unique chromosomes. Chromosome I is metacentric, chromosome II is telocentric, chromosome III is submetacentric, and chromosome IV is acrocentric. Draw a detailed picture of a germ cell from this organism in Metaphase of Mitosis and label all chromosomal and cellular components. Be sure to label each chromosome (I, II, III, or IV) and include the following in your drawing: centrosomes, 3 kinds of microtubules, metaphase/equatorial plate, and plasma membrane. Use the letter p to indicate a paternal chromosome and m to indicate a maternal chromosome.arrow_forwardWhich of the following statements does BEST compare the processes of mitosis and meiosis? Group of answer choices Mitosis involves two division cycles and results in haploid gametes, while meiosis consists of one division cycle and results in a diploid daughter cell Mitosis involves two division cycles and results in diploid daughter cells, while meiosis consists of one division cycle and results in haploid gametes. Mitosis involves one division cycle and results in diploid daughter cells, while meiosis consists of two division cycles and results in haploid gametes. Mitosis involves one division cycle and results in haploid gametes, while meiosis consists of two division cycles and results in diploid daughter cells.arrow_forward

How do these differences contribute/ lead to genetic variation?arrow_forwardThe following pairs of term differentiate mitosis from meiosis. Describe the pair of terms briefly. 1.

Daughter cells vs. 2 daughter cells 5. 2n = 6 vs n = 3arrow_forwardWhat are the major differences between mitosis and meiosis? Explain this both in terms of the different steps of each event and with regards to the final products of each event. Remember to mention the events which are unique to meiosis and why they are significant.arrow_forward
