Webmeiosis. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce … WebRandom, independent assortment during metaphase I can be demonstrated by considering a cell with a set of two chromosomes (n = 2). In this case, there are two possible arrangements at the equatorial plane in metaphase I. The total possible number of different gametes is 2n, where n equals the number of chromosomes in a set.
Web28 feb. 2024 · According to Harvard CyberBridge, “Metaphase 2 occurs after the prophase 2 and before anaphase 2 during overall meiosis 2 processes.” Key Differences between … WebMetaphase of meiosis has two steps such as metaphase-1 and metaphase-2. In meiosis, homologous chromosomes pair with each other (i.e., they form tetrads) and crossing-over occur. Paired chromosomes (bivalents) with four chromatids in each pair line up. In metaphase I of meiosis, tetrads align on the metaphase plate.
