### Answer Explanation

The correct term for the situation where many genes contribute to the expression of a single phenotype is **polygenic** inheritance.

1. **Polygenic**: This refers to the scenario where multiple genes (often located on different chromosomes) influence a singular trait or phenotype. Examples of polygenic traits in humans include height, skin color, and weight, where various alleles from different genes contribute to the final observable characteristic.

2. **Pleiotropy**: In contrast, pleiotropy occurs when a single gene influences multiple phenotypic traits. A classic example of this is the gene responsible for sickle cell anemia, which affects red blood cell shape, but also impacts various other traits and health issues in an individual.

In summary, when discussing multiple genes shaping one phenotype, the correct choice is **polygenic** inheritance.
