Question
Transcribed Image Text:**Mitosis vs Meiosis in Cell Division**
**Overview:**
Mitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction.
**Question:**
What would be a problem if an organism tried to use mitosis for sexual reproduction instead of meiosis?
**Diagrams Explanation:**
1. **Mitosis Diagram:**
- **Parent Cell:** A single parent cell starts the process.
- **DNA Replication:** The parent cell’s DNA duplicates.
- **2 Daughter Cells:** The cell divides to produce two genetically identical daughter cells.
2. **Meiosis Diagram:**
- **Parent Cell:** Begins with a single parent cell.
- **DNA Replication:** The parent cell’s DNA replicates.
- **2 Daughter Cells:** The cell divides first to produce two daughter cells.
- **4 Daughter Cells:** These two daughter cells each divide again, resulting in a total of four genetically diverse daughter cells, each with half the original amount of DNA.
**Source:** U.S. National Library of Medicine
**Analysis:**
If an organism used mitosis for sexual reproduction instead of meiosis, it would create offspring with the same amount of DNA as the parent cells, effectively doubling the chromosome number in each generation. This would lead to genetic abnormalities and is not viable for sexual reproduction.
**Level:** Advanced (Level 3)
