WebMeiosis drives reciprocal genetic exchanges and produces gametes with halved chromosome number, which is important for the genetic diversity, plant viability, and ploidy consistency of flowering plants. Alterations in chromosome dynamics and/or cytokinesis during meiosis may lead to meiotic restitution and the formation of unreduced … WebThis is achieved by meiosis, the reduction division in germ cells. The purpose of meiosis is the production of 4 cells with half the number of chromosomes. Here at the beginning of meiosis, chromosome …
