Unformatted text preview: Bio Study Question for Exam 2 11. During metaphase, the chromosomes complete migration to the middle of the cell.Immediateltly after metaphase, chromosomes line up on an imaginary line and are pulled apart and the two joined sister chromatids are separated. Anequivalent process takes place during meiosis, after metaphase II. After this phase chromosomes are lined up at the middle of the cell and the sister chromatids separate and move to opposite sides of the cell. Ploidy refers to the number of each type of chromosome present. After metaphase in mitosis he ploidy would be 2n because there is the same number of chromosomes as the diploid parent cell.After metaohase in miosis the ploidy would also be 1n because the 4 haploid daughter cells gametes contain one chromosome each. 12. Crossing over does not occur in mitosis because this process is equilavent to meiosis II and crossing over only occurs during meiosis I. Also in mitosis the chromosome don’t pair up when they line up, they line up individually, which means they don’t have a chance to cross over with...
