3.3 Meiosis

Question 1

What are the phases of Meiosis?

Answer 1

Interphase
Prophase I
Metaphase I
Anaphase I
Telophase I
Prophase II
Metaphase II
Anaphase II
Telophase II

Question 2

What happens in Prophase I ?

Answer 2

Chromosome formation, crossing over, spindle fibers forms, nucelus dissolves

Question 3

What happens in Metaphase I?

Answer 3

Homologous pairs randomly line up in the middle of the cell (random orientation)

Question 4

What happens in Anaphase I?

Answer 4

Spindle Fibers shorten and pull homologous chromosomes to opposite ends if the cells

Question 5

What happens in Telophase I?

Answer 5

Spindle fibers disintegrate, chromosomes uncoil and a nuclear membrane forms. Then, cytokinesis occurs and the cell splits.
