Simulate mitosis by drawing and include the following: Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 homologous pairs of chromosomes (the cell has more chromosome pairs, but we are just looking at 2 of them) It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . There should be one gene on each chromosome. Go through...
