Questions and Answers

What is the outcome of crossing over during meiosis?

  • Exchange of genetic material between sister chromatids
  • Random alignment of homologous chromosome pairs
  • Formation of new combinations of alleles on chromatids (correct)
  • Separation of homologous chromosomes

    • How does independent assortment contribute to genetic diversity?

  • Chromatids separate during anaphase I
  • Random alignment of homologous chromosome pairs creates different combinations of alleles in gametes (correct)
  • Homologous chromosomes exchange genetic material
  • Chromosomes align in a non-random manner

    • During meiosis, what happens at the chiasma?

  • Chromosomes condense
