![]() ![]() Metaphase 2: Microtubules are attached to the kinetochores of the centromere on either side of a single chromosome. Metaphase 1:Microtubules of one pole are attached to kinetochores of one of the two chromosomes facing to the same pole. Metaphase 2:Single chromosomes are arranged at the metaphase equator. Metaphase 1:Tetrads are arranged at the metaphase equator. Metaphase 2:Metaphase 2 is associated with meiosis 2. Metaphase 1: Metaphase 1 is associated with meiosis 1. On the other hand, the microtubules of the other pole are attached to the kinetochores of the second chromosome facing towards the second pole.įigure 2: Metaphase 2 Difference Between Metaphase 1 and 2 Origin Microtubules from one pole are attached to kinetochores of one chromosome, facing towards that pole. The chromosome pairs are arranged in equidistant from the poles due to the counterbalance of pulling powers created by microtubules towards the opposing poles. Highly coiled and densed chromosome pairs are attached to the microtubules of the meiotic spindle via kinetochores. ![]() The opposite poles bear centrioles of the cell. Kinetochore is a protein variety which attach the centromere to the microtubules of the spindle. Prior to metaphase 1, kinetochores form around the centromere. What is the difference between Metaphase 1 and 2 What is Metaphase 1ĭuring metaphase 1, homologous pairs of chromosomes (tetrads) are attached to the meiotic spindle at the metaphase plate. The main difference between metaphase 1 and 2 is that chromosomes are attached as homologous pairs at the equator during the metaphase 1 and during metaphase 2, single chromosomes are attached at the equator.ģ. Metaphase 1 is associated with meiosis 1 whereas the metaphase 2 is associated with meiosis 2. In meiosis, two nuclear divisions, meiosis 1 and meiosis 2 occur to produce diploid germ cells. Cell equator is referred to as metaphase plate or the equatorial plate. Membrane nucleus breaks down, and the condensed chromosomes align in the cell equator in metaphase. During metaphase, chromosomes of a cell are condensed to their second-most condensed stage. The four stages of cell division in eukaryotes include prophase, metaphase, anaphase and telophase. Metaphase is one of the four stages of nuclear division in eukaryotic cells. Main Difference – Metaphase 1 vs Metaphase 2 ![]()
