1. What are the main differences between mitosis and meiosis? Include at least four differences.
2. What happens to the chromosomes during the crossing over process?
3. What is the name of the meiosis phase when the pair of homologous chromosomes are located at both poles of the cell?
4. What is the name of the meiosis phase when the sister chromatids are located at both poles of the cell?
5. What would happen if pair of homologous chromosomes do not correctly separate during meiosis?
6. What is the name of a genetic condition where a person has an extra chromosome?
1. The main differences between mitosis and meiosis include:
a. Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse daughter cells.
b. Mitosis involves one round of cell division, while meiosis involves two rounds of cell division.
c. Mitosis produces diploid cells, while meiosis produces haploid cells.
d. Mitosis is involved in growth and repair, while meiosis is involved in sexual reproduction.

2. During the crossing over process, chromosomes exchange genetic material, leading to an increase in genetic diversity.

3. The name of the meiosis phase when the pair of homologous chromosomes are located at both poles of the cell is called metaphase I.

4. The name of the meiosis phase when the sister chromatids are located at both poles of the cell is called anaphase II.

5. If pair of homologous chromosomes do not correctly separate during meiosis, it can lead to aneuploidy, where the resulting cells have an abnormal number of chromosomes.

6. The name of a genetic condition where a person has an extra chromosome is called trisomy, such as Trisomy 21 (Down syndrome).
