Gametic isolation refers to a set of circumstances whereby gametes are isolated or separated from their matches by a medium or distance. This description also refers indirectly to reproductive isolation, in which a gamete cannot interact with the gametes of another species.
Isolation also applies to the practice of separating birds by age group. In large poultry operations, all-in/all-out management styles allow simultaneous depopulation of facilities between flocks and allow time for periodic clean-up and disinfection to break the cycle of disease.
