Meiosis 0.0 / 5 ? BiologyDNA, genetics and evolutionASAQA Created by: Eema003Created on: 29-05-16 20:55 Interphase DNA is replicated. Creates 2 sisters chromatids. Chromatids pair up and join at the centromere. 1 of 4 Division 1 Homologous Chromosomes pair up. Crossing over. Homologous pair separate, with 1 chromosome from each pair going into 1 of 2 daughter cells. (Haploid). 2 of 4 Division 2 Sister Chromatids move apart. 4 cells form. Each with 23 chromosomes. 3 of 4 Genetic variation Crossing over- Equivelent portions of chromatids may be exchanged. Independant segregation- The random distribution and independant assortment of chromosomes 4 of 4
