Definition: Reproductive isolation is the set of mechanisms that prevent different populations or species from interbreeding and producing fertile offspring.

Examples:
1. Temporal isolation — two frog species breed at different times of year, so they never mate.
2. Mechanical isolation — mismatched flower shapes prevent pollen transfer between two plant species.

Usage sentence: Reproductive isolation between the island finch populations eventually produced two distinct species.
