Updated Meiosis

Match the following for mitosis and meiosis.

• Meiosis

• Sister Chromatids (already crossed over) pull apart

• Mitosis & Meiosis

• Homologous Chromosomes pulled apart & Independent assortment

• Anaphase 1 of Meiosis

• PMAT happens once or twice

• Mitosis

• makes 4 genetically different cells

• Anaphase 2 of Meiosis

• makes 2 identical cells

Name this phase of Meiosis:

• Prophase II

• Metaphase I

• Metaphase II

• Anaphase II

In Anaphase II, the _________ separate.

• Homologues

• Sister Chromatids

• Tetrads

• Centrioles

how many chromosomes do human gametes have?

• 46

• 23

• 18

• 36

Crossing over usually occurs between:

• Sister Chromatids

• Homologous Chromosomes

• Alleles

• Non-Homologous Chromosomes

Meiosis is 

• The particular alleles or letter combination
• a form of cell division that results in 4 different daughter cells
• a form of cell division that results in 2 identical daughter cells
• just like mitosis

What phase is this?

Hint: membrane is disappearing

• Interphase II

• Prophase I

• Metaphase I

• Anaphase II
