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.Which of the following statements is not true in comparing mitosis and meiosis? a. Twice the number of cells are produced in meiosis as in mitosis. b. Meiosis is involved in the production of gametes, unlike mitosis. c. Crossing over occurs in meiosis I but not in meiosis II or mitosis. d. Meiosis and mitosis both produce cells that are genetically identical. e.

- 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…A cat germ cell has a haploid number of 19 chromosomes.Complete the following table by stating the number of cells, the number of chromatids, and the number of chromosomes at the end of each of the following stages of meiosis and mitosis. (Please note this is an emply chart, I'm unsure why it got declined last time because it is not graded) Meiosis Meiosis Mitosis Prophase I Telophase I Telophase Number of cells Number of Chromatids Number of ChromosomesThe process of crossing-over occurs during Prophase I of meiosis Prophase II of meiosis Metaphase I of meiosis Anaphase I of meiosis The process of meiosis involves:: one DNA replication and one cell division two DNA replications and two cell divisions one DNA replication and two cell divisions two DNA replications and one cell division Sporic meiosis, where both the haploid and diploid stages of the life cycle are multicellular, is characteristic of animals bacteria fungi plants
