what is the difference between meiosis 1 and 2 quizlet?
211618
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. ... These four daughter cells only have half the number of chromosomes? of the parent cell - they are haploid.
28237
In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II.

C) They are haploid, but the chromosomes are still in duplicated form. Meiosis II is essentially the same as mitosis except that the outcome produces cells that are: A) diploid. ... maternal chromosomes assort independently of paternal chromosomes.

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.

However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.

Mitosis produces 2 identical cells, while meiosis produces 4. Meiosis are genetically different, while mitosis is genetically identical.

No, because DNA is replicated in Interphase first and no interphase stage exists after after Meiosis 1. Describe the main difference between Metaphase 1 and Metaphase 2. In Metaphase 1, paired homologous chromosomes line up along the equator of the cell. ... It is a regular mitosis when chromosomes are not duplicated.

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.
1446388
Which of the following statements describes a major difference between meiosis II and mitosis in a diploid animal? Meiosis II occurs in a haploid cell, while mitosis occurs in diploid cells. A triploid cell contains three sets of homologous chromosomes.
1137479
Meiosis occurs in two stages, called meiosis I and meiosis II, each of which occurs in four phases (prophase, metaphase, anaphase, and telophase). Gametogenesis is the process in which the diploid cells change into mature gametes.
740780
Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. ... In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.
1469141
The main difference between prophase 1 and 2 is that genetic recombination occurs through crossing overs and the “Chiasmata” formation during prophase 1 whereas no genetic recombination is noticed at the prophase 2.

1) Meiosis produces haploid daughter cells; mitosis produces diploid daughter cells. 2) Mitosis consists of one cell division cycle; meiosis includes two cell division cycles.
304281
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis I is a type of cell division unique to germ cells, while meiosis II is similar to mitosis.
80234
Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division). Most of the differences between the processes occur during Meiosis I.

The cells that enter meiosis II are the ones made in meiosis I. 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.
