Question

Use your textbook and any other resources you would like to draw the following scenarios. Use of different colors is recommended for keeping track of chromosomes and chromatids. 1. Draw a diploid cell with n=3 through each step of mitosis (PMAT). Make sure the number of chromosomes is visible and appropriate for each step. 2. Draw a diploid cell with n=3 through each step of meiosis. Color-code your maternal vs. paternal chromosomes so crossing over is visible. Make sure the number of chromosomes is visible and appropriate for each step. 3. Assume the individual whose cell was used in #2 (for meiosis) is a mosquito with a dominant phenotype of a black body. Use Punnett squares or the FOIL method to show how a testcross would identify the genotype of the individual. Upload your final drawing as a PDF file. Lab 6
