frequency-dependent selection


frequency-dependent selection
частотозависимый отбор
Форма отбора, основанная на зависимости адаптивной ценности генотипа от частоты его встречаемости в популяции, - например, при бэйтсоновской мимикрии чем ниже в сравнении с числом мимикрируемой формы количество особей-подражателей, тем выше уровень их приспособляемости.
