Question

EXERCISE IN MITOSIS AND MEIOSIS The cell shown is in Interphase. a) 1) Is the cell haploid or diploid? Explain how you know. b) What is the diploid chromosome number? .. ~ The haploid number? - a Diagram the main events of the process of mitosis in this cell. Label homologous chromosomes, and sister chromatids at each step. Indicate the number of chromosomes and the number of DNA molecules in each cell at each step. 2) 3) Label homologous chromosomes, Diagram the main events of the process of meiosis in this cell. and sister chromatids at each step. Indicate the number of chromosomes and the number of DNA molecules in each cell at each step. 4) The individual from whom the cell was taken is genotype Aa Bb. The different genes are on a) b) c) Diagram the cell showing the location of the alleles of each gene. Repeat question 2) but show all alleles at each step. Repeat question 3) but show all alleles at each step. Show the process of meiosis for all possible ways that chromosomes can align prior to the first meiotic division 5) a) State Mendel's First Law, the Law of Segregation in your own words (don't use the word segregation in your statement of the law). What does the law mean in terms of the gametes produced by an individual. Without the use of diagrams, explain how the behavior of chromosomes in meiosis provides the basis of the law of segregation. b) c) State Mendel's Second Law, the Law of Independent Assortment in your own words (don't use the words independent assortment in your statement of the law) What does the law mean in terms of the gametes produced by an individual. Without the use of diagrams, explain how the behavior of chromosomes in meiosis provides the basis of independent assortment. 6) a) b) c) The Effects of Linkage Modify your model to represent an individual of genotype Aa Ce in which the genes are linked with A and c on one homolog and a and C on the other.

Explanation / Answer

1) a) In interphase, the cell have diploid number of chromosomes. So the given cell is a diploid cell (2n=4)

b) Diploid = 2n = 4 chromosomes

Haploid = n = 2 chromosomes.
