To fill in the Punnett square for a cross between a heterozygous big-footed turtle (Bb) and a small-footed turtle (bb), we start by setting up the square:

```
B | b
-----------------
b | Bb | bb
-----------------
b | Bb | bb
```

Now, we fill in the blanks from your question:

1. **Question Blank 1 of 8**: B
2. **Question Blank 2 of 8**: b
3. **Question Blank 3 of 8**: B
4. **Question Blank 4 of 8**: b
5. **Question Blank 5 of 8**: Bb
6. **Question Blank 6 of 8**: bb
7. **Question Blank 7 of 8**: Bb
8. **Question Blank 8 of 8**: bb

Now, regarding the phenotypes in the F1 generation:

- Bb (big-footed) = 2
- bb (small-footed) = 2

The ratio of possible phenotypes of the F1 generation is:

- Big-footed : Small-footed = 2 : 2, which can also be simplified to 1 : 1.

So the answer for **Question at position 20** is:

**1** big-footed : **1** small-footed.

You can just input the numeric answer for the ratio of big-footed turtles in the fill-in-the-blank, which would be "1".
