• See homogeneous (mathematics) for a number of mathematical usages

Homogeneity has a precise meaning in physics.

In biology homogeneous has a meaning similar to its meaning in mathematics. Generally it means "the same" or "of the same quality or general property", such as a homogeneous sample, homogeneous population, etc.

Homogenous (without the second e) has a similar meaning of being the same throughout, and is perhaps more common in everyday speech. For example homogenised milk is milk which has been processed so that the cream is mixed throughout the milk, rather than being left to settle at the top.
