Meiosis Poster Project Your group will make a poster on one of the following topics: Genetic Variation in Meiosis through Independent Assortment Genetic Variation in Meiosis through Crossing Over Be sure to use the correct set of directions for the poster topic your group is assigned. Posters will be graded on content and neatness. All group members must contribute to the posters. Genetic Variation in Meiosis through Independent Assortment Poster Should Include: A title for your poster A paragraph explaining what independent assortment is and how it produces genetic variation in the gametes (egg or sperm). Make a diagram of a cell undergoing meiosis to illustrate the two possible outcomes through independent assortment (see directions below). The diagram does not need to include every phase, just the starting parent cell and the possible outcomes for the gametes produced. Label and include a definition of each of the following: a homologous pair, sister chromatids and a centromere. In your poster, show a starting cell which is a diploid cell containing two homologous pairs of chromosomes, one pair which is longer and one pair which is shorter. • Use 4 different colors of yarn to represent the chromosomes in different colors, but making the sister chromatids the same color. • Use stickers with letters to represent the different genes on the chromosomes. o The long homologous pair has the gene for flower color (R/r). Long chromosome 1 has the red flower color gene form (R) Long chromosome 2 has the white flower color gene form (r) o The short homologous pair has the gene for plant height (T/t). Short chromosome 1 has the tall gene form (T). Short chromosome 2 has the short gene form (t). o Remember to make sister chromatids identical (same gene form). o Use pieces of clay to represent the centromeres. o Show the 2 possible ways that the 2 pairs of chromosomes can line up during independent assortment and label these two possibilities as option 1 and option 2. o Display the 4 possible gametes that can be produced from these possible arrangements. Genetic Variation in Meiosis through Crossing Over Should Include: A title on your poster A paragraph explaining what crossing over is and how it produces genetic variation in the gametes (egg or sperm). Make a diagram of a cell undergoing meiosis to show the process of crossing over. (See directions below.) Not every phase of meiosis needs to be included, but show the parent cell, the process of crossing over and the possible outcomes for the gametes produced. Label and include a definition of each of the following: a homologous pair, sister chromatids and a centromere. In your poster, show a parent cell which is a diploid cell containing one homologous pair of chromosomes with two different genes labeled (G/g and R/r). • Use 2 different colors of yarn to represent the chromosomes in the pair different colors, but making the sister chromatids the same color. • Use stickers with letters to represent the different genes on the chromosomes. o This chromosome has the genes for pod color (G/g) and seed shape (R/r). Chromosome 1 has the green pea pod gene form (G) and wrinkled seed shape (r). Chromosome 2 has the yellow pea pod gene form (g) and round seed shape (R) o Remember to make sister chromatids identical (same gene form). • Use pieces of clay to represent the centromeres. • In the gametes that are produced, use the different colors of yarn, as well as the letter stickers to indicate the pieces of the chromosome that have been exchanged. (The chromatid strands in which crossing over has occurred will now be composed of two different colors). Make a diagram showing: o The starting cell during prophase I before crossing- over has occurred. o The cell in the process of crossing over. o The four gamete cells that would be produced- with different colors of yarn for the two gametes that would have recombined chromosomes due to crossing over.
