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 ...
How different is telophase 1 from telophase 2?
The key difference between telophase 1 and 2 is that the telophase I is the termination phase of the first nuclear division of meiosis and results in two daughter cells while the telophase II is the termination phase of the second nuclear division of meiosis and results in four daughter cells at the end of the process.
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 is the main difference between metaphase 1 and metaphase 11?
Metaphase IMetaphase IIIt is associated with meiosis I.It is associated with meiosis II.Tetrads are arranged at the metaphase equator.The single chromosome is arranged at the metaphase equator.Metaphase plate is arranged in equidistant from the poles.Metaphase plate rotates 9000C compared to metaphase I.
How does the metaphase of meiosis I differ from that of meiosis II?
Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II. 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.
How is metaphase I different from metaphase I?
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 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 How are they the same?
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 meiosisAll chromosomes form a single plate in metaphaseChromosomes form two parallel plates in metaphase I5 more rows
What happens in metaphase II?
The cell is in metaphase II when the chromosomes align themselves along the metaphase plate through the facilitation of the spindle fibers. The spindle fibers are now attached to the two kinetochores contained in the centromere of each chromosome.
What happens during metaphase II?
During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell.
Which statement describes a difference between meiosis I and meiosis II?
Which statement describes a difference between meiosis I and meiosis II? Homologous chromosomes separate during meiosis I; sister chromatids separate during meiosis II.
How is metaphase 1 of meiosis different than 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 anaphase 1 and 2?
Anaphase 1 and anaphase 2 are two phases in the meiotic division of cells which produces gametes during the sexual reproduction. The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated during anaphase 2.
What is the difference in metaphase between mitosis and meiosis 1 quizlet?
In Metaphase of Mitosis, cells line up in single file. In Mitosis 1 of Meiosis, they line up in homologous pairs.
Answer
because i have read that chromosomes condense in metaphase 1 only and a cell has half the number of chromosomes in metaphase 2.

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.
Which statements describe the differences between metaphase I and metaphase II?
Which statements describe differences between metaphase I and metaphase II? Select two options. Chromosomes line up in the middle in metaphase I only. Chromosomes condense in metaphase I only. A cell has half the number of chromosomes in metaphase II. There are twice the number of cells in metaphase II. Spin dle fibers exist in metaphase II only.
What is the difference between metaphase I and metaphase II?
The following statements describe differences between metaphase I and metaphase II: Chromosomes line up in the middle in metaphase I only, A cell has half the number of chromosomes in metaphase II. [ ]
What is the difference between meiosis and mitosis?
Describe the main differences between meiosis and mitosis. - Meiosis involves two divisions of the nucleus. - Mitosis involves one division of the nucleus. - Meiosis produces four haploid sex cells. - Mitosis produces two diploid cells that are identical to the original cell.
What is the function of meiosis?
Be sure to explain your answer. - Meiosis produces haploid sex cells used in sexual reproduction. - Meiosis ensures that the number of chromosomes after fertilization is the normal diploid number of chromosomes for that organism. - Meiosis ensures that genetic differences result among organisms of the same kind.
