Unformatted text preview: Meiosis is a two-step process consisting of meiosis I and meiosis II. Results in 4 haploid daughter cells, meiosis I divides into haploid and meiosis II replicates similar to mitosis. Genetic Variation Independent assortment: because each homologous pair of chromosomes is independent at meiosis I, assortment is random. Gives a greater number of possible outcomes for daughter cell. Crossing over: produces recombinant chromosomes that combine genes from both parents, during prophase I, non-sister chromatids of homologous chromosomes exchange corresponding segments. Random fertilization: random nature of fertilization adds to genetic variation....
