WebDec 23, 2015 · Meiosis is called the reductional division because is halves the ploidy number. It is also important to note that meiosis only occurs in gametes. In humans, … WebThe main reason why there is a genetic variation in meiosis is because there is what we call crossing over. During the prophase in meiosis I, once the homologous chromosomes pair up and from a tetrad in the process which we call the synapsis, chromatids of the tetrad may exchange parts/ genetic material in the process which is called crossing over. pearington charging station
