Mitosis (2n-2n)PMAT 1X-Asexual-somatic cells: part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.
Meiosis: (2n-n) PMAT 2x- Sexual- Crossing over- Prophase 1- Genetic variation: The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes. Male and female gametes fuse during fertilization, creating a diploid cell with a complete set of paired chromosomes.
