Distinguishing Meiosis I from Meiosis I| How do you know what is meiosis I and what is meiosis II? Here are some hints to help you determine how to identify if a cell is undergoing meiosis I or meiosis II. • In prophase l and metaphase I, the chromosomes are found in their homologous pairs. In prophase Il and metaphase ll, there are single duplicated chromosomes. • In anaphase l and telophase I, the chromosomes are duplicated (shaped like Xs). In anaphase ll and telophase II, the chromosomes are not duplicated. Take a look at the picture, and then answer the questions How many chromosomes will be in the gamete produced when this cell has finished meiosis? O 1 O 4 O 2 O 3 O 6

Figure 13.6 Which of the following statements about nondisjunction is true? Nondisjunction only results in gametes with n+1 or n-1 chromosomes. Nondisjunction occurring during meiosis II results in 50 percent normal gametes. Nondisjunction during meiosis I results in 50 percent normal gametes. Nondisjunction always results in four different kinds of gametes.

Meiosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of meiosis. Make sure you label the alleles for genes on the chromosomes the whole way through - every chromatid should have labeled alleles. For meiosis, both crossing over and independent assortment can occur. For the purpose of this exercise, assume that there is a single crossover event on the long chromosome between the A and D genes. Only show crossing over after its fully occured. There are no crossover events on the short chromosome. Regarding independent assortment, there are two possible outcomes in meiosis if there are two homologous pairs of chromsomes. Include both independent assortment possibilities - one on the left side and one on the right. Fill in the possible gamete genotypes for each outcome. If you do this correctly you should end up with 8 different types of gametes. Image attached for genotypes and alleles. Give me a full explaination of each of…

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?
On the three horizontal lines in the center, label the following stages of Meiosis:Metaphase I, Metaphase II and gametes. • In the top left circle, draw Metaphase I of Meiosis for a cell that is 2n=4 (two large and two small chromosomes). 1) Draw chromosomes as an X or /, not decondensed. 2) Since we are focusing on the DNA, do not draw the nuclear membrane or spindle fibers. 3) For simplicity, do not indicate crossover in your diagrams. 4) Use different colors for each "set" of information (one large and one small chromosome). 5) Using the same genes/alleles as DTL 15 & 16, mark gene locations and label them in each cell. 6) Make sure you show that homologous chromosomes are the same size and sister chromatids are identical. • On the right side of the line, draw the second way homologs could line up Metaphase 1. Make sure that homologs are paired, just flip one of the pairs. ● Draw the resulting chromosomes in Metaphase II and gametes. Notice that there are four types of gametes. In…

What is the relationship between meiosis and fertilization? 3. If cell division during gametogenesis is non-meiotic, what is its consequence to the future generations of diploid organisms? 4. How does non-disjunction in meiosis lead to numerical chromosomal aberration?
Mitosis produces 2 daughter cells that are identical to the starting cell. Explain how meíosis is different using this diagram to help you. 1) How many cells are created through meiosis? 2) Describe the chromosomes in each gamete at the end of meiosis? Are the set of chromosomes in a gamete identical to the starting cell like they are in mitosis? Are there the same number of chromosomes in each gamete as the starting cell?

Lab 11- Mitosis & Meiosis If provided microscope images of plant cells, can you determine if they are in Interphase and/or identify the particular Mitosis stage (Pro, Prometa, Meta, Ana, Telo)? If provided meiosis beads (like what we used in lab), can you look at how they are arranged and determine what meiosis stage is being represented (the stage name and if it's from Meiosis-l or Meiosis-II)?
