What is the different between prophase in mitosis and meiosis?

Answer 1

In metaphase I the tetrads are again arranged across the center by the movements of the kinetochores with the two centromeres opposite each other, but this time the sister chromatids will not be pulled apart as in mitosis.

Answer 2

Mitosis results in two new daughter cells being formed from one parent cell. The daughter cells are identical in both size and genetic make up to the original parent. The daughter cells have the full compliment of chromosomes (46 in humans). This is called the diploid number (n). Mitosis occurs in all somatic cells and is used for growth and cell replacement. Meiosis is the production of four new daughter cells from one parent cells. Meiosis only occurs in gametes (sperm and ova). This process results in the production of four completely different cells. Each new cell has half the compliment of chromosomes this is called the haploid number (2n). In humans the haploid number is 23 chromosomes so when the sperm and egg fuse, the egg has 23 chromosomes and the sperm has 23 chromosomes so the baby (zygote) has half the number of chromosomes from its mother and the other half from its father.

Answer 3

At the end of mitosis the number of chromosomes in both the parent and the daughter cells are the same - 4N to 2 * 2N; whereas at the end of meiosis the number of chromosomes in the meiotic daughter cells are one-quarter the number of chromosomes of the parent cell - 4N to 2 * 2N to 4 * 1N.

Answer 4

During metaphase in mitosis, the duplicated chromosomes line up along the metaphase plate (middle of the cell). Humans have 46 chromosomes. So during metaphase, our duplicated 46 chromosomes would line up along the metaphase plate. Eventually, two daughter cells each with 46 chromosomes will be created.

There are 2 metaphases in meiosis. During Metaphase I, the homologous chromosomes line up on the metaphase plate. So in humans there would be 23 pairs of duplicated chromsomes lining up along the middle of the cell. When the cell divides there will be two daughter cells each containing 23 duplicated chromosomes.

During Metaphase II of meiosis, the 23 duplicated chromosomes would line up along the metaphase plate. The duplicated chromosomes would be separated creating 2 daughter cells each with 23 chromosomes (1/2 the chromosomes of a normal human body cell). Four daughter cells are produced from 1 parent cell, each with 23 chromosomes.

Answer 5

Meiosis produces 4 cells whereas Mitosis only produces 2. Meiosis involves the same stages at Mitosis, but it just does the cycle twice.

Meiosis results in the formation of haploid cells that are different in size and shape whereas mitosis results in the same type of cells.

Answer 6

In mitosis- the chromosomes line up on the metaphase plate. In meiosis- the chromosome pairs line up on either side of the metaphase plate.

Answer 7

Mitosis makes two identical cells

Meiosis makes four different cells

Answer 8

In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.

Answer 9
