Unformatted text preview: human karyotype fig here Paternal Maternal Metaphase 1-Paired homologous chromosomes line up on metaphase plate. Since there are 3 chromosome pairs, there are 8 possible ways for these chromosome pairs to be arranged on the metaphase plate. Three ways are pictured here. This random alignment leads to INDEPENDENT ASSORTMENT. Example of Independent Assortment in cell with 4 chromosomes (2 pair) Example of Independent Assortment in cell with 4 chromosomes (2 pair) Anaphase 1 and Telephase 1 occur leading to the first meiotic division and the rest of meiosis. The end result of MEIOSIS is 4 HAPLOID gamete cells. In our case, the new cells have 3 chromosomes. Diploid number is 6; haploid number is 3. Human Keratype Human Keratype Human haploid number is 23; diploid number is 46....
