Let's address each of the questions step by step based on the information provided regarding the big-footed/small-footed turtle cross.
### Question 18
**What percent of the F1 generation were short?**
In the cross of a heterozygous big-footed turtle (Bb) with a small-footed turtle (bb), the resulting offspring phenotypes will be 50% big-footed (Bb) and 50% small-footed (bb).
**Answer: 50%**
---
### Question 19
**Fill in the blanks that correspond with the missing information in the Punnett square.**
When we cross Bb (top row) with bb (left column), we get:
- 1st Row: Bb, Bb
- 2nd Row: bb, bb
The filled blanks according to this would be:
1. **B**
2. **b**
3. **B**
4. **b**
5. **Bb**
6. **bb**
7. **Bb**
8. **bb**
---
### Question 20
**What is the ratio of possible phenotypes of the F1 generation?**
From the Punnett square:
- 2 big-footed (Bb)
- 2 small-footed (bb)
The ratio of big-footed to small-footed is 2:2, which simplifies to 1:1.
**Answer: 1 big-footed : 1 small-footed**
---
### Question 21
**What is the ratio of possible genotypes of the F1 generation?**
Again from the Punnett square:
- 2 Bb (heterozygous big-footed)
- 2 bb (homozygous small-footed)
The ratios of genotypes would be:
- 2 Bb: 2 bb
This simplifies to 1 Bb : 1 bb.
**Answer: 1 : 1**
---
### Question 22
**What is the genotype in the lower right hand quadrant?**
The lower right-hand quadrant of the Punnett square corresponds to the combination of b (from the small-footed turtle) with b (from the small-footed turtle), which results in:
**Answer: bb**
---
### Question 23
**What is the probability that their next offspring will have big feet?**
The offspring's genotypes will be:
- 2 Bb (big-footed)
- 2 bb (small-footed)
Thus, the probability of having big feet (Bb) is 2 out of 4, which simplifies to 1/2.
**Answer: 1/2**
### Question 18
**What percent of the F1 generation were short?**
In the cross of a heterozygous big-footed turtle (Bb) with a small-footed turtle (bb), the resulting offspring phenotypes will be 50% big-footed (Bb) and 50% small-footed (bb).
**Answer: 50%**
---
### Question 19
**Fill in the blanks that correspond with the missing information in the Punnett square.**
When we cross Bb (top row) with bb (left column), we get:
- 1st Row: Bb, Bb
- 2nd Row: bb, bb
The filled blanks according to this would be:
1. **B**
2. **b**
3. **B**
4. **b**
5. **Bb**
6. **bb**
7. **Bb**
8. **bb**

### Question 20
**What is the ratio of possible phenotypes of the F1 generation?**
From the Punnett square:
- 2 big-footed (Bb)
- 2 small-footed (bb)
The ratio of big-footed to small-footed is 2:2, which simplifies to 1:1.
**Answer: 1 big-footed : 1 small-footed**
---
### Question 21
**What is the ratio of possible genotypes of the F1 generation?**
Again from the Punnett square:
- 2 Bb (heterozygous big-footed)
- 2 bb (homozygous small-footed)
The ratios of genotypes would be:
- 2 Bb: 2 bb
This simplifies to 1 Bb : 1 bb.
**Answer: 1 : 1**
---
### Question 22
**What is the genotype in the lower right hand quadrant?**
The lower right-hand quadrant of the Punnett square corresponds to the combination of b (from the small-footed turtle) with b (from the small-footed turtle), which results in:
**Answer: bb**
---
### Question 23
**What is the probability that their next offspring will have big feet?**
The offspring's genotypes will be:
- 2 Bb (big-footed)
- 2 bb (small-footed)
Thus, the probability of having big feet (Bb) is 2 out of 4, which simplifies to 1/2.
**Answer: 1/2**
