Generating. A cell is 2n = 4 and will soon go through meiosis I and meiosis II, to become four genetically distinct haploid cells. Draw and label all the stages (prophase I, metaphase II, etc.) and the location/distribution of chromosomes using red and blue colors for the chromosomes in cach stage. In at least one of the homologous pairs, show crossing over using two different alleles of your choice. (15 points)

I NEED ANSWERED ASAP!!! First, draw a cell with 6 chromosomes as it moves through the phases of meiosis. Explain what nondisjunction is. Draw and copy a picture of your drawing of your cell with 6 chromosomes to start with as it goes through the phases of meiosis with nondisjunction occurring in one chromosomes pair in meiosis I. Be sure to label the phases and indicate how many chromosomes each resulting cell will have. Label the monosomies vs. trisomies. EXTRA...

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...
