### The completed chart illustrating the differences between mitosis and meiosis is as follows:<br /><br />| Question | Mitosis | Meiosis |<br />|----------|---------|---------|<br />| What is its purpose? | Growth, repair, asexual reproduction | Sexual reproduction |<br />| What cell type(s) undergo this process? | Somatic cells | Germ cells |<br />| Where in the body does it occur? | Throughout the body | Reproductive organs (ovaries and testes) |<br />| What is the number of chromosomes in the original cell? | Diploid (2n) | Diploid (2n) |<br />| What is the ploidy of the original cell? | Diploid (2n) | Diploid (2n) |<br />| What is the number of chromosomes in each daughter cell? How does this relate to that of the original cell? | Same as original (diploid, 2n) | Half of original (haploid, n) |<br />| Timing of replication? | Once before mitosis | Once before meiosis I |<br />| Number of divisions? | One | Two (meiosis I and meiosis II) |<br />| Synapsis of homologous chromosomes involved? | No | Yes |<br />| What is the ploidy of each daughter cell? How does this relate to the original cell? | Diploid (2n), same as original | Haploid (n), half of original |<br />| How many daughter cells are produced? | Two | Four |
Explain
## Step 1: Understand the Purpose of Mitosis and Meiosis<br />### Mitosis is primarily for growth, repair, and asexual reproduction, while meiosis is for sexual reproduction.<br /><br />## Step 2: Identify the Cell Types Undergoing Each Process<br />### Mitosis occurs in somatic (body) cells, whereas meiosis occurs in germ (sex) cells.<br /><br />## Step 3: Determine the Location of Each Process in the Body<br />### Mitosis occurs throughout the body, while meiosis occurs in the reproductive organs (ovaries and testes).<br /><br />## Step 4: Number of Chromosomes in the Original Cell<br />### Both processes start with a diploid cell (2n), which has two sets of chromosomes.<br /><br />## Step 5: Ploidy of the Original Cell<br />### The original cell in both mitosis and meiosis is diploid (2n).<br /><br />## Step 6: Number of Chromosomes in Each Daughter Cell<br />### In mitosis, daughter cells have the same number of chromosomes as the original cell (diploid, 2n). In meiosis, daughter cells have half the number of chromosomes (haploid, n).<br /><br />## Step 7: Timing of Replication<br />### DNA replication occurs once before mitosis and once before meiosis I.<br /><br />## Step 8: Number of Divisions<br />### Mitosis involves one division, while meiosis involves two divisions (meiosis I and meiosis II).<br /><br />## Step 9: Synapsis of Homologous Chromosomes<br />### Synapsis of homologous chromosomes occurs in meiosis but not in mitosis.<br /><br />## Step 10: Ploidy of Each Daughter Cell<br />### In mitosis, daughter cells are diploid (2n), identical to the original cell. In meiosis, daughter cells are haploid (n), containing half the number of chromosomes compared to the original cell.<br /><br />## Step 11: Number of Daughter Cells Produced<br />### Mitosis produces two daughter cells, while meiosis produces four daughter cells.
