Answer 1

Here are the answers to the questions based on the information provided:

### Questions about Guinea Pig Genotypes and Phenotypes:

1. **A hairless guinea pig has the genotype -**
- Answer: **hh** (assuming hairless is recessive).

2. **A guinea pig that does have hair has the genotype -**
- Answer: **HH or Hh** (as both will exhibit the hair phenotype).

3. **What is the phenotypic ratio when two heterozygous guinea pigs are crossed?**
- Answer: **3 Hair : 1 Hairless** (Hh x Hh results in 3 with hair and 1 without).

### Questions about Genotypes & Phenotypes:

4. **Bb - Genotype =**
- Answer: **Heterozygous brown**

5. **bb - Genotype =**
- Answer: **Homozygous blue**

6. **BB - Genotype =**
- Answer: **Homozygous brown**

7. **Tt - Genotype =**
- Answer: **Heterozygous tall**

8. **tt - Genotype =**
- Answer: **Homozygous short**

9. **RR - Genotype =**
- Answer: **Homozygous round**

10. **Rr - Genotype =**
- Answer: **Heterozygous round**

11. **Gg - Genotype =**
- Answer: **Heterozygous green**

12. **gg - Genotype =**
- Answer: **Homozygous yellow**

13. **Bb - Phenotype =**
- Answer: **Brown**

14. **bb - Phenotype =**
- Answer: **Blue**

15. **BB - Phenotype =**
- Answer: **Brown**

16. **Tt - Phenotype =**
- Answer: **Tall**

17. **tt - Phenotype =**
- Answer: **Short**

18. **RR - Phenotype =**
- Answer: **Round**

19. **rr - Phenotype =**
- Answer: **Wrinkled**

20. **Gg - Phenotype =**
- Answer: **Green**

21. **gg - Phenotype =**
- Answer: **Yellow**

### Questions about Genotypes in Circles:

22. **Genotypes that go in the BLUE circles -**
- Answer: **bb** (homozygous recessive blue)

23. **Genotypes that go in the RED circles -**
- Answer: **BB** or **Bb** (homozygous and heterozygous for brown)

24. **Genotypes that go in the PURPLE circles -**
- Answer: **Tt** or **TT** (tall plants)

25. **Genotypes that go in the GREEN circles -**
- Answer: **tt** (homozygous short)

### Questions about Punnett Squares:

26. **What percentage of the offspring will be tall?**
- Answer: **75%** (if two heterozygous plants are crossed, Tt x Tt).

27. **What percentage of the offspring will be short?**
- Answer: **25%**

28. **Click on the square that is "short" (homozygous recessive).**
- Click on the square corresponding to **tt** in the Punnett square.

29. **Click on the square that homozygous tall.**
- Click on the square corresponding to **TT** in the Punnett square.

30. **What percentage of the offspring will be tall?**
- Answer: **100%** (TT x tt results in all offspring being Tt).

31. **What percentage of the offspring will be short?**
- Answer: **0%** (Tt x Tt results in no tt offspring).

32. **What percentage of their offspring will have green peas?**
- Answer: **0%** (two yellow plants would both be gg, so all offspring would also be gg, yellow).
