WebDuring what stage of meiosis is genetic variation increased? By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells.Recall that the point of crossing over is to increase genetic diversity. If crossing over did not occur until sometime during meiosis II, sister chromatids, which are identical, … WebWithout genetic variation, some key mechanisms of evolutionary change like natural selection and genetic drift cannot operate. There are three primary sources of new genetic variation: Mutations are changes in the information contained in genetic material. (For most of life, this means a change in the sequence of DNA.)
