Short questions

• Meiosis 1

  • chromosomes are visible (interphase)
  • double-stranded chromosomes
  • crossing over is taking place
  • homologous pairs line up at the equator
• State the ways variation occurs during meiosis:

  • crossing over
  • random arrangement
• Meiosis 2

  • recombinant chromosomes visible
  • no crossing over takes place
  • single chromosomes line up at the equator (no longer in homologous pairs)
