how many daughter cells are produced in meiosis 1 and 2?
211200
Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell. However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell.

5.5 The Two Parts of Meiosis-Meiosis II In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.

Preparing for mitosis, a cell produces a copy of its DNA. ... Homologous pairs are separated, and the two resulting daughter cells have half as many chromosomes per cell. The two daughter cells produced from meiosis I enter meiosis II where they each are divided again to produce a total of four haploid daughter cells.

There will be 2 cells formed at the end of meiosis 1. Meiosis 1 is a reductional division. So a 2n diploid cell will be reduced to 2 haploid ie. n, cells.

In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.

The cell copies its chromosomes, but then separates the 23 pairs to ensure that each daughter cell has only one copy of each chromosome. A second division that divides each daughter cell again to produce four daughter cells. See below for more detailed descriptions of mitosis and meiosis.

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.

These cells are haploid—have just one chromosome from each homologue pair—but their chromosomes still consist of two sister chromatids. In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes. Prophase II: Starting cells are the haploid cells made in meiosis I.

Two daughter cells are the final result from the mitotic process while four cells are the final result from the meiotic process. For organisms that reproduce via sexual reproduction, daughter cells result from meiosis.

The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. The main differences between mitosis and meiosis occur in meiosis I.

In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. So at the start of meiosis I you have diploid cells but through reductive division you finish the process with haploid cells. In theory it's both.

Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell. Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I.

At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

1 Answer. During meiosis 1, the parent cell with double the normal amount of chromosomes, splits into two diploid cells (have enough chromosomes to survive). During meiosis 2, the two diploid cells each split into two haploid cells (have half the amount of chromosomes to survive). Meiosis ends with four haploid cells.

A total of four haploid daughter cells are produced during the course of meiosis II. Meiosis is the process whereby chromosomes are copied, paired up and separated to create eggs or sperm.

Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
