1. the ability of different species or varieties to breed together and produce fertile offspring
Usage: biology; genetics

Examples

• The interfertility between the two plant species allowed botanists to create a new hybrid variety.
• Scientists studied interfertility in closely related animal populations to understand evolutionary relationships.
• The lack of interfertility between the species suggested they had diverged millions of years ago.
• Interfertility tests are used to determine whether organisms belong to the same biological species.
• The interfertility of certain dog breeds demonstrates how selective breeding can maintain genetic compatibility.
