Question

• Compare the features of
• Metaphase in mitosis
• Metaphase I
• Metaphase II

25
Answer

• Mitosis Metaphase? diploid chromosomes line up at
  the equator of the cell
• Metaphase I? homologus chromosomes line up along
  the equator
• Metaphase II?same as mitosis except the
  chromosomes are haploid
