Each cell is haploid containing one-half the number of chromosomes as the original cell. 3. Genetic Composition. Mitosis: The resulting daughter cells in mitosis are genetic clones (they are genetically identical). Web5. Some of these homologs have one or more chiasmata, an X shaped region where a genetic rearrangement has occurred. This formation occurs because of sister chromatid cohesion, where a gene that has been given to the homologous pair in synapsis is still bonded to the corresponding part on the sister chromatid of its former chromatid. 6.
