During metaphase of meiosis 2, or metaphase II, there are 3 major points. 1st is the chromosomes are positioned on the metaphase plate as in mitosis. 2nd is, because of the crossing over in meiosis I, the two sister chromatids of each chromosome are not genetically identical. 3rd is the kinetochores of sister chromatids are attached to microtubules extending from opposite poles.
What else can I help you with?
Do homologous chromosomes pair up during metaphase 2 as they do in metaphase 1?
No, homologous chromosomes do not pair up during metaphase 2 as they do in metaphase 1. In metaphase 2, individual chromosomes line up along the metaphase plate.
During metaphase 2, do homologous chromosomes pair up?
During metaphase 2, homologous chromosomes do not pair up. Instead, individual chromosomes line up along the metaphase plate in preparation for separation during anaphase 2.
How does the number of chromosomes in metaphase of mitosis compare to the number of duplicated chromosomes in metaphase 2 of meiosis?
In metaphase of mitosis, the number of chromosomes is equal to the number of duplicated chromosomes. However, in metaphase 2 of meiosis, the number of chromosomes is half that of the duplicated chromosomes, since meiosis involves two rounds of cell division to produce haploid cells.
What is the correct order for the sequence of meiosis?
Interphase Prophase 1 Metaphase 1 Anaphase 1 Telophase 1 Cytokinesis 1 Prophase 2 Metaphase 2 Anaphase 2 Telophase 2 Cytokinesis 2
In what ways are metaphase 1 and metaphase 2 similar in the process of cell division?
Metaphase 1 and metaphase 2 are similar in that both stages involve the alignment of chromosomes along the cell's equator. This alignment ensures that each daughter cell receives the correct number of chromosomes during cell division.
What. Happens directly after metaphase?
Anaphase
What happens after pro-phase?
Metaphase
Do homologous chromosomes pair up during metaphase 2 as they do in metaphase 1?
No, homologous chromosomes do not pair up during metaphase 2 as they do in metaphase 1. In metaphase 2, individual chromosomes line up along the metaphase plate.
Differences between metaphase 1 and metaphase 2?
1. In metaphase 1 spindle formation is completed In metaphase 2 spindle formation take place 2. Bivalent are involved in metaphase 1 Bivalents are not involved in metsphase 2
Describes what happens during metaphase?
Chromosomes align along equator, or metaphase pate of cell.
What is is the difference between metaphase 1 and 2?
Metaphase 1 The chromosomes line up on the equatorial (metaphase) plate. Metaphase 2 Kinetochores of the paired chromatids.
During what phase do the chromosomes move to the center of the cell aligned on the spindle apparatus?
This happens during metaphase. I remember this phase because it is the move phaseof mitosis. The m from move matches the m from metaphase.In mitosis, it happens during metaphase.In meiosis, it happens twice and occurs in metaphase 1 and metaphase 2.
What metaphase does nondisjunction occur in Metaphase 1 or metaphase 2?
Non-disjunction is the failure of a pair of chromosomes or chromatids to separate. Since this happens in both metaphase I and II, non-disjunction can occur in either stage.In metaphase I it is the failure of the two homologous chromosomes in the pair to separate. In this case all of the gametes will be affected.In metaphase II it is the failure of the two sister chromatids to separate. In this case only half of the gametes are affected.Non-disjunction is the cause of a number of genetic conditions eg Down syndrome, Triple-X syndrome.See http://en.wikipedia.org/wiki/Nondisjunction
What happens in annaphase?
after metaphase the chromosomes rip or break in the middle after they have lined up in metaphase and start to drift to opposite sides of the nucleus
What is a metaphase?
A metaphase cell is a stage in the cell cycle. It happens when a chromosome is most highly condensed and hence it is easiest to distinguish and to study the cell.
What happens in metaphase 1?
pairs of homologous chromosomes move to the equator of the cell
What happens during division?
prophase, metaphase, anaphase, telophase (including cytokinesis)
