Plural of gamodeme; populations of organisms that can interbreed and share genes through sexual reproduction.
From Greek 'gamos' (marriage/sexual union) + 'demos' (people/population). Emerged in early 20th-century population genetics to describe breeding populations as distinct units.
This term is crucial to understanding how evolution actually works—scientists realized that genes don't just float freely in a species, but stay trapped within groups of organisms that can actually mate with each other, creating invisible boundaries in nature.
