Question

bobtrails in cats are recessive. TT,Tt,tt

Answer 1

In genetics, traits can be categorized based on their inheritance patterns. In this scenario, we have a gene determining the presence of bobtails in cats, where the trait for bobtails (let's assume "bobtail" is the recessive trait) is indicated by the "t" allele, and the dominant trait (normal tail) is represented by "T".

Here's a breakdown of the genotypes:

- **TT**: Homozygous dominant (normal tail)
- **Tt**: Heterozygous (normal tail, but carries the recessive bobtail allele)
- **tt**: Homozygous recessive (bobtail)

Since bobtails (tt) are recessive, they will only express the bobtail trait when both alleles are "t". If either allele is "T", the cat will display the dominant normal tail trait.

### Crosses Involving Bobtail Trait

1. **TT x TT**:
- Offspring: 100% TT (normal tails)

2. **TT x Tt**:
- Offspring: 50% TT (normal tails), 50% Tt (normal tails, carriers)

3. **Tt x Tt**:
- Offspring: 25% TT (normal tails), 50% Tt (normal tails, carriers), 25% tt (bobtail)

4. **Tt x tt**:
- Offspring: 50% Tt (normal tails, carriers), 50% tt (bobtail)

### Summary of Results
Through these crosses, we can see how the recessive bobtail trait can appear depending on the genotypes of the parent cats. If you have a specific question or scenario in mind for further assistance, feel free to ask!
