chromosome number of 4. Now try it when the chromosome number is 3.
Step by step
Solved in 3 steps with 2 images
- In the following diagram, designate each daughter cell as diploid (2n) or haploid (n).A cell has a diploid number of 6 (2n = 6). a. Draw the cell in metaphase of meiosis I. b. Draw the cell in metaphase of mitosis. c. How many chromosomes are present in a daughter cell after meiosis I? d. How many chromatids are present in a daughter cell after meiosis II? e. How many chromosomes are present in a daughter cell after mitosis? f. How many pairs of homologous chromosomes are visible in the cell in metaphase of meiosis I?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.
- A cell (2n = 4) has undergone cell division. Daughter cells have the following chromosome content. Has this cell undergone mitosis, meiosis I, or meiosis II?Make a simple sketch of meiosis in a diploid germ cell that has one pair of homologous chromosomes. Now try it when the cell has theee chromosomes.Make a simple sketch of meiosis in a diploid germ cell that has one pair of homologous chromosomes. Now try it when the cell has three homologous chromosomes
- The cells seen below were stained with Acetocarmine. Scales indicate 20 micrometers. Please explain what stages of meiosis are visible in cells labelled A through F. Give reasons for each stage of meiosis you consider the cell to be in.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? Starting cell's chromosomes: 1А, 1B, 2A, 2B Interphase After the S phase of interphase: 4 pairs of sister chromatids 1A 1A 1B 1B 2A 2A 2B 2B Meiosis has 2 rounds of cell division 1A, 1A, 1B, 1B, 2A 2B 2A 2B tv MacBook Air DII DD 80 888 F9 F10 F6 F7 F8 F4 F3 * #3 2$ % & 8 9 3 4 E T. Y F G J K * CO Rz e 50 μm Figure 3. Grasshopper testis with differential staining and viewed under a microscope. Encircle the cell and label the specific stage in the meiosis it displays. Identify as many as you can witha minimum of two cells representing different stages. Make sure to specify whether the stage belongs to meiosis I or II. If you identify a cell at prophase I, then specify the substage.
- Consider a cell in which nondisjunction occurs for all chromosomes during meiosis I. What would be the result of this event? Multiple Choice two diploid gametes two haploid gametes and one aneuploid gamete with an extra set of chromosomes four aneuploid gametes four haploid gametesA gamete cell has 34 chromosomes. How many chromosomes will be in a somatic cell? How many tetrads are formed in meiosis 1?Assume that cell does mitosis Assume that cell does meiosis What is the diploid number of chromosomes in this organism? Give the number of chromosomes and the number of DNA molecules per cell present at the stages represented. I tried to solve them, but I'm not sure what I did right and what was wrong. Please correct it for me. See that attached photo.
