Metaphase 1 vs. Metaphase 2

Key Differences

In metaphase 1, two members of each bivalent repel each other and switch within the path of the opposite poles. In metaphase 2, the centromere divides and two chromatids of each chromosome separate and switch within the path of the poles.

In metaphase 1, chromosomes are launched by the spindle fibers. In metaphase 2, after separation each chromatid turns into chromosome.

In metaphase 1 of meiosis 1, homologous chromosomes are separated whereas in metaphase 2 of meiosis 2, sister chromatids are separated.

Metaphase 1 stage current in meiosis 1 stage that’s why typically often known as metaphase 1, whereas metaphase 2 current in meiosis 1 that’s why typically often known as metaphase 2.

The plane of metaphase plate in metaphase 1 is perpendicular as compared with the plane of the metaphase plate in metaphase 2.

In metaphase 1, chromosomes tetrads aligned on metaphase plate whereas, in metaphase 2, chromosomes organized on metaphase plate as jus like throughout the mitosis with solely sister chromatids.

In metaphase 1, each pole receives half the number of chromosomes whereas in metaphase 2 have the similar number of chromosomes nevertheless with a single chromatid.

Metaphase 1

Metaphase 1 is the next state to prophase 1 when prophase 1 crossing over will get achieved, and tetrads switch within the path of a plan typically often known as metaphase plate. This metaphase plate is positioned between two poles of the cell. Here the spindle fibers are linked to the centromeres of each of the bivalents, and every kinetochores of each sister chromatid pair are then shifted in the direction of the similar pole. Consequently, every kinetochores bind to the spindle fibers to find out the similar pole. This is the true between mitosis and meiosis as members of the each chromosome pair separate from each other throughout the subsequent stage of meiosis that is anaphase 1. Two chromosomes and four chromatids in full from each guardian can set up on each side of the cell and produce the variations in chromosomal distribution in daughter cells after meiosis 1.

Metaphase 2

Metaphase 2 is the second stage in meiosis 2 the place each of the 2 daughter cells generated by the secondary gems cells. In this stage, the spindle as soon as extra attracts the chromosomes to the metaphase plate. Unlike metaphase 1 the place two kinetochores of centromere bind to spindle fibers on comparable poles, proper right here they bind from the opposite poles as happen throughout the case of mitotic metaphase and moreover related to the kinetochore-microtubule coming from that pole. This, in the end, separates the sister chromatids of each chromosome in the midst of the anaphase 2. According to Harvard CyberBridge, “Metaphase 2 occurs after the prophase 2 and before anaphase 2 during overall meiosis 2 processes.”
