ЧТО ОЗНАЧАЕТ СЛОВО LINEBREEDING
инбридинг
Инбридинг - это производство отпрысков от спаривания или размножения людей или организмов, которые тесно связаны генетически, в отличие от ауткроссинга, что относится к спариванию не связанных между собой лиц. По аналогии, этот термин используется для размножения человека, но чаще всего относится к генетическим нарушениям и другим последствиям, которые могут возникать в результате кровосмесительных сексуальных отношений и кровного родства. Инбридинг приводит к гомозиготности, что может увеличить шансы отпрыска, пострадавшего от рецессивных или вредных черт. Это в целом приводит к снижению биологической пригодности населения, то есть его способности выжить и размножаться. Человек, который наследует такие вредные черты, называется инбредным. Предотвращение таких вредных рецессивных аллелей, вызванных инбридингом, является основной избирательной причиной ауткроссинга. Инбридинг - это метод, используемый в селекционном разведении. В животноводстве селекционеры могут использовать инбридинг, когда, например, пытаются установить новую и желательную черту в запасе, но им необходимо будет наблюдать за нежелательными характеристиками у потомства, которые затем могут быть устранены путем дальнейшего селективного размножения или отбраковки.
