The diploid cell in your model will have two pairs of homologous chromosomes. In order to keep track of the pairs, you will make one pair longer than the other. The beads will represent genes. Use the large sheet of paper to represent the cell. Part A: Interphase Just before meiosis begins, the chromosomes are replicated. 1. Use ten beads and a centromere of one color to construct the long chromosome. Use ten beads and a centromere of a second color to construct the second chromosome in the long pair. Make a drawing of the chromosomes in the space below. 2. For the second pair of chromosomes, use only five beads. 3. Now model the replication of the chromosomes. Make a drawing of your model in the space below. Part B: Meiosis I During meiosis I, the cell divides into two diploid daughter cells. 4. Pair up the chromosomes to form tetrads. Use the longer tetrad to model crossing-over. Make a drawing of the tetrads in the space below.

umm:

This is an assignment you have to do; since you have the materials.
