In the chart below, briefly describe what occurs in each stage of MEIOSIS:
Phase
STAGES OF MEIOSIS
What Happens At That Phase
14.
The cell grows and doubles its DNA
Prophase I
15.
20.
The homologous chromosomes line up in the middle.
Anaphase I
21.
Telophase I
22.
16.
The cell splits into two cells.
17.
23.
Metaphase II
18.
24.
The chromosome’s chromatid arms are pulled apart
toward opposite ends of the cell.
19.
25.
Cytokinesis II
The two cells split into four cells.
