The separation that different types of chromosomes creates the difference in between metaphase 1 and metaphase 2. The difference between metaphase 1 and metaphase 2 is the metaphase 1 has actually the same variety of chromosomes together the initial cells, whereas, metaphase 1 that meiosis has half the number of chromosomes.
You are watching: What is the difference between metaphase 1 and 2
|Basis the Distinction||Metaphase 1||Metaphase 2|
|Definition||Metaphase 1 is the next state to prophase 1 as soon as prophase 1 cross over it s okay accomplished, and also tetrads move towards a plan known together metaphase plate.||Stage wherein bivalents i ordered it on the metaphase plate and also linked to the totally established meiotic spindle|
|Chromosomes Position||The spindle fibers carry chromosomes||chromatid becomes chromosomes ~ separation of spindle fibers|
|Number of Chromosomes||Each pole receives fifty percent the variety of chromosomes||Also, have the same variety of chromosomes but with a solitary chromatid|
|Bivalent Repletion||Two members of each bivalent repel every other and also move in the direction of the the opposite poles||Centromere divides and two chromatids of every chromosome separate and move towards the poles|
|Name Reason||Metaphase 1 stage uncovered in meiosis 1 phase that’s why well-known as metaphase 1||Metaphase 2 uncovered in meiosis 1 that’s why well-known as metaphase 2.|
What is Metaphase 1?
Metaphase 1 is the following state to prophase 1 as soon as prophase 1 crossing over gets accomplished, and also tetrads move towards a setup known together metaphase plate. This metaphase plate is located between two poles the the cell. Right here the spindle yarn are attached to the centromeres of each of the bivalents, and also both kinetochores of each sister chromatid pair space then shifted toward the very same pole. Consequently, both kinetochores tie to the spindle yarn to create the very same pole. This is the actual difference in between mitosis and also meiosis together members the the each chromosome pair different from each other in the next stage of meiosis that is anaphase 1. Two chromosomes and also four chromatids in full from either parent deserve to arrange ~ above either next of the cell and produce the distinctions in chromosomal distribution in daughter cell after meiosis 1.

What is Metaphase 2?
Metaphase 2 is the 2nd stage in meiosis 2 where each the the 2 daughter cells produced by the secondary gems cells. In this stage, the spindle again paint, etc the chromosomes come the metaphase plate. Unequal metaphase 1 where 2 kinetochores the centromere tie to spindle yarn on exact same poles, right here they tie from opposing poles as take place in the instance of mitotic metaphase and also attached come the kinetochore-microtubule coming from the pole. This, in the end, separates the sisters chromatids of every chromosome during the anaphase 2. Follow to Harvard CyberBridge, “Metaphase 2 occurs after the prophase 2 and before anaphase 2 during overall meiosis 2 processes.”
Key Differences between Metaphase 1 and Metaphase 2In metaphase 1, every pole receives fifty percent the number of chromosomes when in metaphase 2 have actually the same variety of chromosomes but with a solitary chromatid.In metaphase 1, chromosomes are brought by the spindle fibers. In metaphase 2, after separation each chromatid becomes chromosome.In metaphase 1 that meiosis 1, homologous chromosomes space separated when in metaphase 2 of meiosis 2, sister chromatids space separated.In metaphase 1, two members of every bivalent repel every other and move towards the the contrary poles. In metaphase 2, the centromere divides and two chromatids of each chromosome separate and also move in the direction of the poles.Metaphase 1 stage found in meiosis 1 stage that’s why well-known as metaphase 1, if metaphase 2 discovered in meiosis 1 that’s why recognized as metaphase 2.In metaphase 1, bag of chromosomes space arranged on the metaphase bowl while that are changed to metaphase 2 where only chromosomes space arranged on the metaphase plate.The plane of metaphase key in metaphase 1 is perpendicular as contrasted to the plane of the metaphase bowl in metaphase 2.In metaphase 1, chromosomes tetrads set on metaphase plate whereas, in metaphase 2, chromosomes arranged on metaphase plate together jus choose in the mitosis with just sister chromatids.
