A particular species has three homologous pairs. One is metacentric, one is acrocentric and one is telocentric. Below, please draw the chromosomes of one cell of this species during the following three divisional phases. Explain why these three metaphases are different. What is the role each plays in mitosis and each division of meiosis? (Please be certain to illustrate the number of chromatids in each chromosome.)

a. Metaphase of Mitosis

b. Metaphase of Meiosis I

c. Metaphase of Meiosis II

Answer #1

Solution

  • In metaphase of mitosis- there are 2 sister chromatids per chromosome because chromosomes are duplicated. Chromosome located at equator .
  • In metaphase of meiosis I - there are 2 homologous chromosome with 2 sister chromatids per duplicated chromosome. here homologous chromosome lie at equator with crossing over completed.
  • In metaphase of meiosis II- there are 2 sister chromatid per duplicated chromosome. Each sister chromatid is genetically different due to crossing over.

1. Consider a cell that has 2N= 6 chromosomes. We can refer to these chromosomes as letters, using upper and lower case to represent homologous pairs. (Chromosome A is homologous to Chromosome a). So the entire set of chromosomes (the genotype) would be: Aa; Bb; Cc; a) Draw a cell of genotype Aa; Bb; Cc; in anaphase of mitosis. Label all chromosomes. b) Draw a cell of genotype Aa; Bb; Cc; in anaphase I of meiosis. Label all chromosomes.

Which choices accurately match each of the cellular processes to the stage of meiosis in which it occurs? Select all that apply. Microtubules pull homologous chromosomes toward opposite poles in anaphase I. Sister chromatids move toward opposite poles of the cell in anaphase II. Crossing over occurs between homologous chromosomes in prophase II. Homologous chromosomes undergo synapsis in prophase II. 2. Consider a diploid organism with a haploid complement of 4 chromosomes in its gametes. At meiotic prophase I, how...
