Question

For each genotype below, indicate whether it is a heterozygous (He) OR homozygous (Ho).

TT _Ho__ Bb __He___ DD _____ Ff ____ tt _____ dd _____
Dd _____ ff _____ Tt _____ bb ____ BB _____ FF _____

Which of the genotypes in #1 would be considered purebred? ____TT__________________________

Which of the genotypes in #1 would be hybrids? _____Bb_____________________________________

Answer 1

Here's the classification of the genotypes you provided:

1. **TT** - Homozygous (Ho)
2. **Bb** - Heterozygous (He)
3. **DD** - Homozygous (Ho)
4. **Ff** - Heterozygous (He)
5. **tt** - Homozygous (Ho)
6. **dd** - Homozygous (Ho)
7. **Dd** - Heterozygous (He)
8. **ff** - Homozygous (Ho)
9. **Tt** - Heterozygous (He)
10. **bb** - Homozygous (Ho)
11. **BB** - Homozygous (Ho)
12. **FF** - Homozygous (Ho)

### Purebred Genotypes:
- The genotypes that are considered purebred (homozygous) are:
- **TT**
- **DD**
- **tt**
- **dd**
- **ff**
- **bb**
- **BB**
- **FF**

### Hybrid Genotypes:
- The genotypes that are considered hybrids (heterozygous) are:
- **Bb**
- **Ff**
- **Dd**
- **Tt**

So, the answers to your specific questions would be:

- **Purebred genotypes:** **TT, DD, tt, dd, ff, bb, BB, FF**
- **Hybrid genotypes:** **Bb, Ff, Dd, Tt**
