- structural rearrangements
Хромосомные мутации — структурные изменения хромосом, возникающие вследствие перемещения или выпадения хромосомных сегментов после разрывов хромосом и соединения их концов (межгенные мутации). Х. м. могут происходить как в пределах одной хромосомы, так и между гомологичными или негомологичными хромосомами. В любом случае это перемещение или потеря значительных по размерам генных блоков и соответственно изменение соотношения групп сцепления. В зависимости от типа воссоединения после разрывов различают инверсии, транслокации, нехватки и дупликации.
