During which stage of meiosis do sister chromatids line up at the equator of the cell?
metaphase II
What phase do homologous chromosomes line up?
metaphase I
In what stage of mitosis do chromosomes line up along a cell’s equator?
metaphase
Which of the following phases is described by the statement homologous chromosomes line up along equator of the cell?
17. Tetrads line up along the equator during this phase: METAPHASE I 18. At the end of meiosis I, 2 daughter cells are created.
What phase does cytoplasm divides 2 daughter cells are formed?
cytokinesis
What is the difference between meiosis 1 and meiosis 2?
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.
Why are there two stages of meiosis?
These goals are accomplished in meiosis using a two-step division process. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
What is the difference between mitosis and meiosis division?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Why interphase between meiosis I and meiosis II is short?
First thing to remember is that interphase is a stage associated with replication of DNA, and growth. So there is no further need of replication or growth. Hence between meiosis I and meiosis II , there is no interphase.
Is there an interphase between meiosis 1 and meiosis 2?
First thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II , there is no interphase.
What is the phase that occurs between meiosis I and meiosis II?
It is preceded by interphase, specifically the G phase of interphase. Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase….How is Meiosis I Different from Meiosis II?
| Meiosis I | Meiosis II |
|---|---|
| Crossing over happens | Crossing over does not happen |
Is DNA is replicated between meiosis I and meiosis II?
DNA replication occurs only once during meiosis. The process takes the form of one DNA replication followed by two successive nuclear and cellular divisions (Meiosis I and Meiosis II).
Why is DNA not replicated after meiosis?
Is the DNA replicated after Meiosis 1? Why or why not? No, because DNA is replicated in Interphase first and no interphase stage exists after after Meiosis 1.
What does meiosis II mean?
Meiosis II is the second division in meiosis in which chromatids of each chromosome are segregated equally into daughter cells. No DNA replication occurs during the interphase which precedes meiosis II. By metaphase II, each chromosome is aligned at the metaphase plate. Anaphase II is the third step in meiosis II.
What is a major difference between meiosis II and mitosis?
The major difference between meiosis II and mitosis is the ploidy of the starting cell. Meiosis II begins with two haploid cells, which have half the number of chromosomes as somatic cells. This is because they will develop into gametes. Mitosis begins with a diploid cell.
What are similarities between mitosis and meiosis II What is the significant difference between them?
Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent. Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells.
What is the difference between meiosis II and mitosis answers com?
The main difference between meiosis II and mitosis is that the meiosis II essentially occurs in haploid cells that have gone through meiosis I whereas the mitosis mainly occurs in diploid cells. Moreover, meiosis II occurs in the production of gametes in sexual reproduction while mitosis occurs in asexual reproduction.
What part of meiosis is most similar to mitosis?
Meiosis II
What is the significance of crossing over in meiosis I?
Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
Which of the following stage is similar in mitosis and meiosis?
Explanation: So everything in meiosis 2 (prophase2 ,metaphase 2, anaphase 2, telophase 2) is same as mitosis.
