BREEDER

A 'breeder' is a person who practices the vocation of mating carefully selected specimens of the same breed to reproduce specific, consistently replicable qualities and characteristics.
This might be as a farmer, agriculturalist, or hobbyist, and can be practiced on a large or small scale, for food, fun, or profit.
A 'breeder' is also a derogatory term used by homosexuals when regarding non-homosexuals.
