### Polygenic Traits Explanation
Polygenic traits are those that are influenced by multiple genes. These traits often show continuous variation and are affected by both genetic and environmental factors.

### Trait Analysis
1. **Blood Type**: This trait is determined by a single gene (ABO gene), so it is not polygenic.
2. **Height**: Height is influenced by multiple genes, making it a classic example of a polygenic trait.
3. **Sickle-Cell Disease**: This condition is caused by a mutation in a single gene (HBB), so it is not polygenic.
4. **Cystic Fibrosis**: Like sickle-cell disease, cystic fibrosis is caused by a mutation in a single gene (CFTR), thereby not polygenic.

### Conclusion
Among the options provided, **height** is the trait that is polygenic in humans.
