AnswersDriveAfter mitosis two identical cells are created with the same original number of chromosomes, 46. Haploid cells that are generated through meiosis, such as egg and sperm, only have 23 chromosomes, because, remember, meiosis is a "reduction division."
In respect to this, how many divisions are involved in meiosis?
Back to Top. Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division). Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells.

What is the final phase of mitosis?
Telophase is technically the final stage of mitosis. Its name derives from the latin word telos which means end. During this phase, the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.

Is cell division mitosis?
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

How many nuclear divisions are involved in meiosis?
This is half the number of chromosome sets in the original cell, which is diploid. Comparing Meiosis and Mitosis: Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct.
5
What are the two types of cell division?
In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).
6
How many cell divisions are involved in mitosis?
Mitosis is a single cell division - one diploid cell divides into two diploid cells. Meiosis consists of one diploid cell undergoing two cell divisions yielding four haploid cells usually called gametes.
7
What is the number of cell divisions in meiosis?
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.
8
What is the difference between mitosis and meiosis?
Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical. In mitosis the daughter cells are identical to the parent as well as to each other.

What are the types of cells that undergo mitosis?
MEIOSIS IS FOUND TO OCCUR IN HUMANS, ANIMALS, AND PLANTS. MITOSIS IS FOUND IN SINGLE CELL SPECIES. MITOSIS UNDERGO CELLS AND ORGANISMS THAT CAN REPRODUCE ASEXUALLY AND CREATE IDENTICAL COPIES OF THEIR DNA. MEIOSIS USES ORGANISMS THAT RELY ON SEXUAL REPRODUCTION, BUT THE PROCESS OF MITOSIS IS STILL NEEDED FOR GROWTH.

What are the eight stages of meiosis?
8 Stages of Meiosis
- Prophase I. The chromosomes condense, and the nuclear envelope breaks down.
- Metaphase I. Pairs of homologous chromosomes move to the equator of the cell.
- Anaphase I. Homologous chrmosomes move to the oppisite poles of the cell.
- Telophase I and Cytokinesis.
- Prophase II.
- Metaphase II.
- Anaphase II.
- Telophase II and Cytokinesis.

What is the process of cell division called?
The mitosis division process has several steps or phases of the cell cycle—interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis—to successfully make the new diploid cells. When a cell divides during mitosis, some organelles are divided between the two daughter cells.
12
What is the purpose of division in mitosis and meiosis?
The purpose of meiosis is to reduce the normal diploid cells (2 copies of each chromosome / cell) to haploid cells, called gametes (1 copy of each chromosome per cell). In humans, these special haploid cells resulting from meiosis are eggs (female) or sperm (male).
13
How many times do the cells divide in meiosis?
Meiosis, on the other hand, is a special form of mitosis that occurs only in a special subset of our cells to form eggs and sperm. In meiosis, one cell divides twice in a row to form four daughter cells from one cell (Figure 1B). Those cells are then modified to become eggs or sperm.
14
How many stages are there in mitosis?
Phases of mitosis. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
15
What are the different stages of meiosis?
Therefore, meiosis includes the stages of meiosis I (prophase I, metaphase I, anaphase I, telophase I) and meiosis II (prophase II, metaphase II, anaphase II, telophase II).
16
Is meiosis asexual?
Meiosis does not occur during asexual reproduction. Meiosis is the process of producing gametes (eggs and sperm). Mitosis, on the other hand, is simply the process of cell division. This is the process that animals are going through during regeneration.
17
What is the steps of cell division with two identical daughter cells are formed?
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
18
What types of cells are produced by mitosis?
There are two types of cell division. Mitosis is used for growth and repair and produces diploid cells identical to each other and the parent cell. Meiosis is used for sexual reproduction and produces haploid cells different to each other and the parent cell.
19
What is meiosis division?
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid.
