B-Meiosis1. Using the same set of wires, pair the homologous chromosomes.What stage is this?1.a. Assume crossing-over between non-sister chromatids (use the longgreen wire with a red segment at the tip and the long red wire with a greensegment at the tip).What stage is this?1.b. Draw and label the chromosomes showing the interchanged segments.Chromosome numberChromosome compositionLStage1.c. What is the significance of crossing over?2. Draw and label the chromosome at metaphase I.Metaphase IChromosome numberChromosome composition2.a. How is this stage different from metaphase of mitosis?

Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake. (There needs to be a model drawing) What would a 2n=10 cell look like during prophase I? What would that cell look like during metaphase I? At the end of meiosis I? During metaphase II? At the end of meiosis II?
Can you guys complete this diagram for me? The instructions are “To draw the chromosomes when appropriate and separate the chromosome pairs or the chromatids at the correct stages. The two long chromosomes are a homologous pair and the two short chromosomes are a homologous pair (the thickness of the line indicates which parent the chromosomes cane from-thin for mom and thick for dad. Note that you have only one of each thickness with each homologous pair. Feel free to use a color scheme instead of thickness as you draw, but you need to keep one long and one short chromosome the same color and the second long and short chromosomes a second color so that crossing over can be visualized easily.”
