Answer:

MEIOSIS:

- Each replicated chromosome pairs with its corresponding homologous chromosome

- Tetrads form and crossing over sometimes occur

- Paired homologous chromosome line up across the center of the cell.

- Four haploid daughter cells form that are not identical to the parent cell

MITOSIS:

- Homologous chromosomes do not pair

- One row of chromosomes line up at the center of the cell.

- The cell nucleus divides only once

- Two diploid daughter cells form that are identical to the parent cell.

Explanation:

Mitosis and Meiosis are the two cellular divisions that occur in living organisms. Mitosis is the kind of cell division that produces two diploid daughter cells that are genetically identical to the parent cell while Meiosis produces four haploid daughter cells (gametes) that are genetically different from the parent cell.

Based on the general description of the two cell divisions above, the following events take place in them respectively:

1) MEIOSIS:

- Each replicated chromosome pairs with its corresponding homologous chromosome (similar but non-identical chromosome from each parent).

- Tetrads form and crossing over sometimes occur. Tetrads are the structures that form when two homologous chromosomes pair while crossing over is the exchange of chromosome segment between two non-sister chromatids of homologous chromosomes. These two only occur during meiosis.

- Paired homologous chromosome line up across the center of the cell during metaphase I of meiosis.

- Four haploid daughter cells form that are not identical to the parent cell. Note that meiosis reduces the chromosomal number of the parent cell by half.

2) MITOSIS:

- Homologous chromosomes do not pair during mitosis.

- One row of replicated chromosomes (sister chromatids) line up at the center of the cell during metaphase.

- The cell nucleus divides only once in mitosis as opposed to twice during meiosis.

- Two diploid daughter cells form that are identical to the parent cell. Note that mitosis retains the chromosomal number of the parent cell.

Mitosis occur in somatic cells while meiosis occur in the germ cells to produce gametes.

MITOSIS:

  • Two diploid daughter cells form that are genetically identical the parent cell.
  • Homologous chromosomes do not pair in mitosis.
  • In mitotic cells one row of chromosomes line up at the center.
  • The nucleus of the cell divides only once.

MEIOSIS:

  • Four haploid daughter cells form that are genetically different to the parent cell.
  • Each homologous chromosome  pairs after replication.
  • Tetrads or group of four cell form and crossing over sometimes occur.
  • Paired homologous chromosome line up across the center of the cell.

Therefore, mitosis occur in somatic cells while meiosis occur in the germ cells.
