The separation of different types of chromosomes creates the difference in between metaphase 1 and metaphase 2. The difference in between metaphase 1 and also metaphase 2 is that metaphase 1 has the same variety of chromosomes as the initial cells, whereas, metaphase 1 of meiosis has fifty percent the variety of chromosomes.

Comparison Chart
| Basis that Distinction | Metaphase 1 | Metaphase 2 |
| Definition | Metaphase 1 is the following state to prophase 1 as soon as prophase 1 cross over it s okay accomplished, and also tetrads relocate towards a setup known together metaphase plate. | Stage whereby bivalents arranged on the metaphase plate and also linked to the completely established meiotic spindle |
| Chromosomes Position | The spindle fibers bring chromosomes | chromatid becomes chromosomes ~ separation of spindle fibers |
| Number that Chromosomes | Each pole receives fifty percent the variety of chromosomes | Also, have actually the same variety of chromosomes but with a solitary chromatid |
| Bivalent Repletion | Two members of each bivalent repel every other and also move towards the opposite poles | Centromere divides and two chromatids of each chromosome separate and also move in the direction of the poles |
| Name Reason | Metaphase 1 stage uncovered in meiosis 1 phase that’s why well-known as metaphase 1 | Metaphase 2 discovered in meiosis 1 that’s why known as metaphase 2. |
What is Metaphase 1?
Metaphase 1 is the next state to prophase 1 as soon as prophase 1 crossing over gets accomplished, and also tetrads relocate towards a arrangement known as metaphase plate. This metaphase key is located in between two poles of the cell. Here the spindle yarn are linked to the centromeres of every of the bivalents, and both kinetochores of each sister chromatid pair are then shifted toward the very same pole. Consequently, both kinetochores tie to the spindle fibers to establish the same pole. This is the genuine difference in between mitosis and also meiosis together members the the each chromosome pair separate from each other in the next stage the meiosis that is anaphase 1. Two chromosomes and also four chromatids in complete from either parent deserve to arrange ~ above either side of the cell and produce the differences in chromosomal circulation in daughter cells after meiosis 1.

What is Metaphase 2?
Metaphase 2 is the second stage in meiosis 2 whereby each that the two daughter cells created by the secondary gems cells. In this stage, the spindle again paint, etc the chromosomes to the metaphase plate. Unlike metaphase 1 where two kinetochores the centromere bind to spindle yarn on exact same poles, right here they bind from opposing poles as happen in the instance of mitotic metaphase and additionally attached come the kinetochore-microtubule coming from that pole. This, in the end, off the sister chromatids of every chromosome throughout the anaphase 2. Follow to Harvard CyberBridge, “Metaphase 2 wake up after the prophase 2 and before anaphase 2 during overall meiosis 2 processes.”
Key Differences in between Metaphase 1 and Metaphase 2
In metaphase 1, each pole receives half the variety of chromosomes if in metaphase 2 have actually the same number of chromosomes yet with a single chromatid.In metaphase 1, chromosomes are carried by the spindle fibers. In metaphase 2, ~ separation each chromatid becomes chromosome.In metaphase 1 of meiosis 1, homologous chromosomes are separated when in metaphase 2 of meiosis 2, sister chromatids are separated.In metaphase 1, two members of each bivalent repel each other and move in the direction of the the opposite poles. In metaphase 2, the centromere divides and two chromatids of every chromosome separate and move towards the poles.Metaphase 1 stage discovered in meiosis 1 stage that’s why well-known as metaphase 1, while metaphase 2 found in meiosis 1 that’s why well-known as metaphase 2.In metaphase 1, pairs of chromosomes are arranged top top the metaphase key while the are adjusted to metaphase 2 where just chromosomes room arranged top top the metaphase plate.The airplane of metaphase bowl in metaphase 1 is perpendicular as contrasted to the airplane of the metaphase plate in metaphase 2.In metaphase 1, chromosomes tetrads to adjust on metaphase plate whereas, in metaphase 2, chromosomes i ordered it on metaphase plate as jus choose in the mitosis with only sister chromatids.Video Explanation
