The key difference between metaphase 1 and 2 is that in metaphase 1, homologous chromosomes pair up at the metaphase plate while in metaphase 2, single chromosomes line up at the metaphase plate. Meiosis is the process that converts a diploid cell into four haploid cells during the gamete formation.
What are the stages of metaphase?
Metaphase. In metaphase, the microtubules pull on the chromosomes with equal force, and the chromosome moves to the center of the cell. Anaphase. The anaphase is marked by the splitting of the sister chromatids. These sister chromatids then become the chromosomes of the daughter nuclei. Telophase. The telophase is the final phase of mitosis.
How is telophase 1 different from telophase 2?
Telophase 1is the final stage of meiosis I while telophase 2 is the final stage of meiosis II. Furthermore, telophase 1 results in two daughter cells, whereas telophase 2 results in four daughter cells at the end of the process. Therefore, this is a key difference between telophase 1 and 2. Moreover, in telophase 1, each chromosome has both ...
What are some facts about metaphase?
What is a Metaphase Plate?
- Metaphase Stage of Mitosis. Metaphase is the second step of mitotic division, which occurs right after prophase. ...
- Formation of a Metaphase Plate. The formation of the metaphase plate, also the equatorial plate, is dependent on the mechanical forces of the microtubule spindle fibers generated from the centrosome.
- Stages of Mitosis. ...
How do you identify metaphase?
Metaphase is marked by the alignment of chromosomes at the center of the cell, half way between each of the mitoic spindle poles. Movement is mediated by the kinetochore microtubles, which push and pull on the chromosomes to align them into what is called the metaphase plate. See also what is bivariate.
Which statement describes difference between metaphase 1 and metaphase 2?
Metaphase 1 is associated with meiosis 1 whereas the metaphase 2 is associated with meiosis 2. The main difference between metaphase 1 and 2 is that chromosomes are attached as homologous pairs at the equator during the metaphase 1 and during metaphase 2, single chromosomes are attached at the equator.
What makes metaphase of meiosis 1 and meiosis 2 different from each other?
The main difference between metaphase of meiosis I and II is that in meiosis I, the homologous chromosomes, which are chromosomes that contain the same genes but are of different parent origins, are still together, whereas in meiosis II, only one of the homologous chromosomes remains in each daughter cell.
Which of the following is a difference between Phase 1 and Phase 2 of meiosis?
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.
How does metaphase in meiosis I and meiosis II differ quizlet?
How does metaphase in meiosis I and meiosis II differ? Homologous chromosomes line up in meiosis I and duplicated chromosomes line up in meiosis II.
What is the major difference between metaphase 1 and metaphase 2 quizlet?
Describe the main difference between Metaphase 1 and Metaphase 2. In Metaphase 1, paired homologous chromosomes line up along the equator of the cell. However, in mitosis and Metaphase 2, it is sister chromatids that line up along the equator of the cell.
What is the difference between metaphase in mitosis and metaphase 2 in meiosis?
Hint: Meta means second and phase means stage, hence metaphase is the second stage of meiosis and mitosis....Distinguish between metaphase of mitosis and metaphase I of meiosis.Metaphase of mitosisMetaphase I of meiosisIndividual chromosome align at metaphase plateTetrad of chromosomes lie at the metaphase plate.5 more rows
How is metaphase 1 of meiosis different from metaphase of mitosis?
Metaphase I in Meiosis The homologous pair is a representation of the same DNA but has different alleles. The homologous pairs will attach to each other during metaphase I and they undergo the alignment on the metaphase plate, unlike in mitosis where the sister chromatids are the ones that align on the metaphase plate.
What is the difference between metaphase of mitosis and metaphase one of meiosis?
In metaphase 1 the pairs of chromosomes referred to as bivalents are totally condensed. Moreover the in metaphase 1 of meiosis there is no centromere division whereas in metaphase of mitosis it does. They align on the metaphase plate in between the poles.
What is the Difference Between Metaphase 1 and 2?
Metaphase of the meiosis 1 is known as metaphase 1 while metaphase of the meiosis 2 is known as meiosis 2. In metaphase 1, pairs of homologous chromosomes line up at the middle of the cell while single chromosomes line up at the middle in metaphase 2. This is the difference between metaphase 1 and 2.
What is Metaphase 1?
Metaphase 1 is the metaphase of meiosis 1. During this phase, the pairs of homologous chromosomes arrange on the metaphase plate of the cell, and then they bind to the meiotic spindle through centromeres. At this moment, the centrioles can be seen at the opposite poles of the dividing cell.
What is the metaphase of meiosis 2?
The metaphase found in meiosis 2 is known as metaphase 2. The events happening in metaphase 2 are similar to the metaphase of the mitosis. During the metaphase 2, single chromosomes arrange in the metaphase plate. Hence it is different from the metaphase 1 since pairs of homologous chromosomes arrange in the metaphase plate.
What is the stage of cell division in which the chromosomes arrange along the metaphase plate?
Hence, metaphase is the stage of cell division in which the chromosomes arrange along the Metaphase plate. Metaphase 1 can be found in meiosis I while metaphase 2 can be found in meiosis II. Metaphase 1 and 2 are different from each other.
How many phases are there in meiosis?
In each meiotic cycle, there are four main phases. They are prophase, metaphase, anaphase and telophase. Metaphase 1 belongs to meiosis 1, and metaphase 2 belongs to meiosis 2.
Which stage of the cell contains half of the chromosomes that of the parent cell?
Then to each centromere of the chromosome, spindle fibres from each pole attach. At this stage, the cell contains half of the chromosomes that of in the parent cell. Metaphase 2 occurs after prophase 2. Anaphase 2 is the next phase after metaphase 2.
Which stage of the cell contains a full set of chromosomes?
The pairs of homologous chromosomes get attached to the spindle fibres from each pole, at the opposite sides. At this stage, the cell contains a full set of chromosomes. Metaphase 1 occurs after prophase 1. Anaphase 1 is the next phase after metaphase 1.
Answer
because i have read that chromosomes condense in metaphase 1 only and a cell has half the number of chromosomes in metaphase 2.
