Unformatted text preview: vision of the genetic material so that both daughter cells have the even amount of chromosomes. Chromosomes exist in homologous pairs in diploid organisms In each homologous pair of chromosomes, one member is derived from each parent Sex- determining chromosomes are not usually homologous yet behave as homologs during meiosis Each diploid organism contains two copies of each gene Members of each pair of genes need not be identical Alleles: alternative forms of same gene. The centromere can be in various places along the chromosomes. By arresting cells in metaphase, we can stop the spindle fibers form forming- cannot move forward. We can then see distinct chromosomes, cut these out, line these up, and designate the number to the chromosome in order to see the individuals genetic material. The mitotic cell cycle: Interphase: S phase in order to synthesize the DNA, the DNA must be fully synthesized (and correctly so) 2 gap phases (G1 and G2) for growth G0 is a point during G1 where cells withdraw from...
