Questions and Answers

What is the result of meiosis in terms of daughter cells and chromosomes?

  • Eight identical daughter cells, each with double the number of chromosomes of the parent cell
  • Three non-identical daughter cells, each with the same number of chromosomes as the parent cell
  • Two identical daughter cells, each with the same number of chromosomes as the parent cell
  • Four non-identical daughter cells, each with half the number of chromosomes of the parent cell (correct)

During which phase of meiosis does crossing over occur?

  • Anaphase I
  • Metaphase II
  • Prophase I (correct)
  • Prophase II

What is synapsis in the context of meiosis?

  • The close association of homologous chromosomes during prophase I (correct)
  • The alignment of chromosomes at the metaphase plate in pairs
  • The division of the cytoplasm following meiosis
  • The random distribution of homologous chromosome pairs to daughter cells
