Questions and Answers

What happens during telophase I of meiosis?

  • Nuclear membranes form around the chromosome clusters at opposite ends of the cell (correct)
  • Chromatids separate into individual chromosomes
  • Chromosome pairs line up in the middle of the cell
  • Spindle fibers begin to form out of centrioles

    • What is the result of cytokinesis in meiosis II?

  • Separation of chromosome pairs into individual chromatids
  • Formation of two diploid cells
  • Attachment of spindle fibers to chromosome pairs
  • Formation of four haploid gamete cells (correct)

    • Which statement is true about prophase II of meiosis?

  • Spindle fibers pull chromatids toward opposite ends of each cell
  • Chromosome pairs separate into individual chromatids
  • Nuclear membrane dissolves and chromosome pairs line up in the middle of each cell (correct)
  • Crossing-over occurs between chromatids
