To solve this problem, we need to look at the "Answer Key" provided in the top half of the worksheet. This key shows exactly how the chromosomes should look during each stage of Meiosis I and Meiosis II.
Here is the step-by-step logic to match the bottom images to the correct labels:
1. Analyze the Top Row (Meiosis I)
*
First Image (Left): The chromosomes are inside a circle (nucleus). They look like X-shapes (two sister chromatids) and are mixed up. You can see lines (spindle fibers) starting to form. This matches the first image in the "Prophase I" box in the answer key.
* *Label:*
Prophase I
*
Second Image (Middle): The X-shaped chromosome pairs have lined up right in the center of the cell. There are two pairs side-by-side. This matches the image in the "Metaphase I" box.
* *Label:*
Metaphase I
*
Third Image (Right - implied by arrow): Although cut off, the blue arrow points to the next stage. In the answer key, after Metaphase I comes Anaphase I, where the whole X-shapes are pulled apart to opposite sides.
* *Label:*
Anaphase I
2. Analyze the Bottom Row (Meiosis II)
Now we look at the second set of images below the first row. These represent the cells dividing again.
*
First Image (Left): We see two separate circles now. Inside each, there are just two single X-shaped chromosomes floating around. They are not lined up yet. This matches the "Prophase II" box in the answer key.
* *Label:*
Prophase II
*
Second Image (Middle): In these two cells, the single X-shaped chromosomes have moved to the exact center line of each cell. This matches the "Metaphase II" box.
* *Label:*
Metaphase II
*
Third Image (Right - implied by arrow): The arrow points to the next step. According to the answer key, the centers of the X-shapes split, and the single legs (chromatids) are pulled apart. This corresponds to the "Anaphase II" box.
* *Label:*
Anaphase II
Summary of the Sequence:
The arrows show the process flowing from left to right.
1. Start with
Prophase I (Chromosomes condense).
2. Move to
Metaphase I (Pairs line up in middle).
3. Next is
Anaphase I (Pairs separate).
4. Then
Prophase II (Two new cells form, chromosomes ready).
5. Then
Metaphase II (Single chromosomes line up in middle).
6. Finally
Anaphase II (Chromatids separate).
Final Answer:
The correct order for the phases shown in the bottom section, following the blue arrows from left to right, is:
Top Row:
1.
Prophase I
2.
Metaphase I
3.
Anaphase I
Bottom Row:
1.
Prophase II
2.
Metaphase II
3.
Anaphase II
