Homologous chrom- osomes do not pair. Homologous chromo- somes pair (synapse). Chromosomes line up individually . Paired homologous chromosomes (bivalents) line up. Mitosis: 1 division Meiosis: 2 divisions Note: Diagrams begin with a diploid cell that has 2 pairs of chromosomes (2n = 4). Chromosome #: 2n = 4 8 chromatids Chromosome #: 2n = 4 8 chromatids Chromosome #: 2n = 4 8 chromatids Chromosome #: 2n = 4 8 chromatids Chromosome #: 2n = 4 8 chromatids

Unformatted text preview: chromosomes separate. Chromatids separate. Chromatids separate (like in anaphase of mitosis). Daughter cells are identical to parent cell. Daughter cells are NOT identical to parent cell: half the # chromosomes; vary from each other in genetic information. Chromosome # at each pole: 2n = 4 Chromosome # in each daughter cell: 2n = 4 Chromosome # at each pole: 1n = 2, 4 chromatids at each pole Chromosome # at each pole and future daughter cell: 1n = 2...
