Simulate meiosis by drawing One pair of chromosomes and no crossing over Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 1 pair of homologous chromosomes It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . Go through the steps of meiosis. Be sure to show and label these in your pictures: Label homologous chromosomes and sister...

Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...

Crossing-Over in Meiosis Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to half the number in the original cell. The parent cell is diploid (2n), and it begins meiosis with a replicated set of chromosomes. During meiosis, this parent cell Homologou will divide twice to create four haploid (1n) cells. pairs During prophase I of meiosis I, homologous pairs of chromosomes pair up and stick together to form tetrads through the process...
