Review for Mastery - 07.01 Meiosis

Crossing over only occurs during (a)  

• Prophase 1
• Prophase 2
• Metaphase 1
• Metaphase 2

Organize these options into the right categories

Groups:

(a) Prophase 1

,

(b) Metaphase 1

,

(c) Anaphase 1

,

(d) Telophase 1

• Homologous chromosomes line up in the middle

• nuclear membrane reappears

• crossing over and recombination

• tetrad chromosomes seperate into pairs

At which point is the cell a haploid? Click on the correct hotspot to select your answer.

(read carefully) A major difference between Mitosis and Meiosis is...

• Meiosis produces 2 daughters cells and Mitosis produces 4 daughter cells.

• Mitosis has Daughter cells are genetically different and Meiosis has Daughter cells are genetically identical.

• Both mitosis and meiosis involve diploid parent cell

• Mitosis produces diploid body cells (somatic) and Meiosis produces haploid (gamete) sex cells.

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in (a)   sex cells.

What is the main goal of both mitosis and meiosis?

• To produce food

• To destroy old cells

• To create energy

• To create new cells

What type of cells does mitosis create?

• Gametes

• Body cells

• Stem cells

• Nerve cells

During which phase do chromosomes match up with homologous pairs in meiosis?

• Telophase

• Anaphase

• Metaphase

• Prophase

What happens during the process called crossing over?

• Genetic information is exchanged

• DNA is replicated

• Chromosomes are destroyed

• Cells stop dividing

How many non-identical haploid cells are created at the end of meiosis?

• Five

• Four

• Three

• Two
