What happens during interphase before meiosis begins?

• Cells divide into two

• DNA is replicated

How is Metaphase I different from metaphase in mitosis?

• Metaphase I involves paired homologous chromosomes lining up, while mitosis involves individual chromosomes.
• Metaphase I occurs in somatic cells, while mitosis occurs in germ cells.
• Both Metaphase I and mitosis involve individual chromosomes lining up.
• Metaphase I has no chromosome alignment, while mitosis does.
