How does metaphase 1 differ from metaphase in mitosis?
In mitosis metaphase the mitotic spindel attaches to one side of a pair of chromosomes and seperates them so that one chromosome ends up on each side. In metaphase 1 of meiosis, the mitotic spindel only attaches to one pair of chromosomes from one side, so that when anaphase occures that pair of chromosomes will end up on one side. overall - mitosis metaphase- chromosomes split - meiosis metaphase 1- chromosome pair stay together and end up one side of the cell.
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.
Which letter represent metaphase 1?
The letter "D" represents metaphase 1 in meiosis. During metaphase 1, homologous chromosome pairs line up at the cell's equator.
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
What are the 9 stages of meiosis?
Prophase 1 , Metaphase 1 , Anaphase 1 , Telophase 1 & Cytokinesis, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2 & Cytokinesis
What happens in metaphase 1?
pairs of homologous chromosomes move to the equator of the cell
What. Happens directly after metaphase?
Anaphase
What happens after pro-phase?
Metaphase
How does metaphase 1 differ from metaphase in mitosis?

In metaphase 1 of meiosis, the mitotic spindel only attaches to one pair of chromosomes from one side, so that when anaphase occures that pair of chromosomes will end up on one side. overall - mitosis metaphase- chromosomes split - meiosis metaphase 1- chromosome pair stay together and end up one side of the cell.
Describes what happens during metaphase?
Chromosomes align along equator, or metaphase pate of cell.
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
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.
What does metaphase 1 look like?
Metaphase 1 looks like a group of bivalents. This is because the spindle fibers get aligned and arranged via a bipolar attraction. They end up along the equatorial line.
Bivalents align at metaphase plate?
Metaphase 1
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 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
