That's a good way to think about it, but not quite technically accurate. Here's a breakdown:

A hybrid is:

* The offspring of parents with different genotypes. Genotype refers to the specific combination of alleles an individual has for a trait.

* Not necessarily different alleles for the specific trait in question. While a hybrid might have different alleles for a particular trait, it's more broadly defined as the offspring of parents with differing genetic makeup in general.

Example:

Let's say you have a plant with purple flowers (genotype PP) and a plant with white flowers (genotype pp). The offspring (hybrid) would have the genotype Pp, resulting in purple flowers because purple is dominant. While the parents have different alleles for the flower color trait, the hybrid still exhibits the dominant trait.

Key Point:

The term "hybrid" doesn't specifically require that the parents have different alleles for a specific trait. It's more about the parents having differing genetic combinations overall.
