Get Chapter 10 Section 1 Meiosis

Meiosis 1. starts with a diploid cell, separates homologous chromosomes, and produces 2 haploid cells. Meiosis 2. separates sister chromatid, each cell produced in meiosis 1 is divided into 2, so produces 4 haploid cells which will then mature to sperm or egg cells.

In this process, we begin with a cell with double the normal amount of DNA, and end up with 4 non-identical haploid daughter gametes after two divisions. There are six stages within each of the divisions, namely prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis.

Meiosis I is the initial round of cell division, during which homologous pairs are separated. The pairing of homologous chromosomes, crossing over, and genetic recombination that occurs during Meiosis I results in two daughter cells with half the number of chromosomes.

There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.

Meiosis I is the initial round of cell division, during which homologous pairs are separated. The pairing of homologous chromosomes, crossing over, and genetic recombination that occurs during Meiosis I results in two daughter cells with half the number of chromosomes.

In this video Paul Andersen explains the major phases of meiosis including: interphase, prophase I, metaphase I, anaphase I, telophase I, cytokinesis, interphase II, metaphase II, anaphase II, and telophase II.

What is Meiosis? Meiosis is the process in which a single cell divides twice to form four haploid daughter cells. These cells are the gametes – sperms in males and egg in females. The process of meiosis is divided into 2 stages. Each stage is subdivided into several phases.

Meiosis I, the first meiotic division, begins with prophase I. During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.

In meiosis I, homologous chromosomes separate resulting in a reduction of ploidy. Each daughter cell has only 1 set of chromosomes. Meiosis II, splits the sister chromatids apart.

Phases of mitosis Late G2 phase. The cell has two centrosomes, each with two centrioles, and the DNA has been copied. ... Early prophase. ... Late prophase (prometaphase). ... Metaphase. ... Anaphase. ... Telophase. ... Cytokinesis in animal and plant cells.

In meiosis I, homologous chromosomes separate resulting in a reduction of ploidy. Each daughter cell has only 1 set of chromosomes. Meiosis II, splits the sister chromatids apart.

Meiosis II Prophase II. Spindle fibers reform and attach to centromeres in prophase II. Metaphase II. The chromosomes align on the metaphase plate during metaphase II in preparation for centromeres to divide in the next phase. Anaphase II. ... Telophase II and Cytokinesis.

Meiosis I segregates homologous chromosomes, which are joined as tetrads (2n, 4c), producing two haploid cells (n chromosomes, 23 in humans) which each contain chromatid pairs (1n, 2c). Because the ploidy is reduced from diploid to haploid, meiosis I is referred to as a reductional division.
