What stage will the chromosome number 1st become a haploid cell (HALVED)?

• Prophase II

• Prophase I

• Metaphase I

• Anaphase I

Put the following events of Meiosis in order. Starting with a diploid cell and ending with meiosis

• Chromosomes line up in pairs at the metaphase plate

• Homologous chromosomes are pulled apart and separated into 2 different cells

• 4 unique haploid cells are formed

• Chromosomes condense and perform crossing over

• Sister Chromatids are ripped apart at the centromere

Is the diagram Mitosis or Meiosis? AND Is it a Diploid or Haploid cell?

• Mitosis AND Diploid

• Mitosis AND Haploid

• Meiosis AND Diploid

• Meiosis AND Haploid
