A species is diploid containing three chromosome pairs.  Draw what the chromosomes would look like in the following phases of the cell cycle. a. G1     b. G2

Determine the haploid and diploid numbers, respectively, of the chromosomes in the cell division process illustrated above. Select one: a. 8 and 4 b. 2 and 4 c. 4 and 8 d. 4 and 2

This diagram shows an animal cell in meiosis I during crossing over and synapsis. A single tetrad is shown with a pair of homologous chromosomes that have been duplicated as sister chromatids. Red chromosomes indicate maternal DNA, and blue chromosomes indicate paternal DNA.  Use the passage to answer the question. Once the animal cell has completed meiosis II:   A. half of the gametes will contain recombinant chromosomes.   B. none of the gametes will contain recombinant chromosomes.   C. all of the gametes will contain maternal DNA.   D. all of the gametes will contain paternal DNA.

Using the symbols above: 1. Given: Adult diploid cell (2n = 8) 2. Show the condition of the chromosomes in the following Mitosis phases (illustrate):                 a. prophase                 b. metaphase                 c. anaphase                 d. telophase/cytokinesis

A cell is shown during the anaphase stage of mitosis. Which of the following statements best explains what would be different if the diagram showed anaphase I of meiosis instead of anaphase of mitosis? Select one: a. Homologous chromosomes would be moving to the same end of the cell. b. Homologous chromosomes would form a tetrad. c. Each chromosome would have two sister chromatids. d. The sister chromatids would be pulled apart.

Humans cells normally have 46 chromosomes (2n). Specify the number of chromosomes present at each of the following stages. In your answers, determine diploid or haploid number of chromosomes and the count the chromatids as chromosomes. For example: anaphase I of meiosis: 46 (2n) = 92    a. metaphase I of meiosis b. metaphase of mitosis c. telophase I of meiosis d. telophase II of meiosis

Draw a diagram of the cell cycle and label the phases (G1, S, G2, M). Indicate the phase when chromosome duplication occurs.

If a diploid organism has 14 chromosomes (2n=14) a.  How many chromosomes will its gametes have?                                                            b.  After meiosis I during gamete formation, how many chromosomes are in each daughter cell?    c.  After meiosis I during gamete formation, how many chromatids are in each daughter cell?

If you are studying a diploid organism that has 14 pairs of chromosomes.   How many chromatids will this cell have in the G2 phase   ?   How many chromatids will the gamete of this organism have
