additive theorem

теорема сложения
Эмпирическое правило, согласно которому на трехлокусном участке А-В-С (не включающем центромеру) соотношение частот кроссинговера подчиняется арифметическим правилам: например, частота рекомбинаций между А и С равна сумме частот рекомбинаций на участках А-В и В-С (см. также map contraction и map expansion).

Теорема сложения — эмпирическое правило, которое гласит, что расстояние в морганидах (см. Моргана единица) на трехлокусном участке А-B-C между генами А и С равно сумме расстояний между генами А и В и между генами В и С, если ген В расположен между генами А и С, или разнице между этими расстояниями, если ген В расположен вне отрезка АС. Т. с. использовалась при составлении хромосомных карт на основе учета кроссинговера.
