Att de europeiska kungahusen under l\u00e5ng tid r\u00f6rde sig med en begr\u00e4nsad upps\u00e4ttning gener har man k\u00e4nt till, men nu har en studie r\u00e4knat ut precis hur inavlat det spanska kungahuset von Habsburg en g\u00e5ng var. M\u00e5nga makar hade till en femtedel identiska gener, skriver Vetenskapsradion p\u00e5 sin n\u00e4tupplaga.<\/p>\n

\u00c4tten von Habsburg regerade i Spanien p\u00e5 15- och 1600-talen och hade m\u00e5nga kusinbr\u00f6llop. Spanska forskare har nu r\u00e4knat ut att flera som gifte sig sannolikt delade mer \u00e4n 20 procent av generna med varandra.<\/p>\n

Enligt forskarna f\u00f6rklarar inaveln varf\u00f6r den siste kungen blev infertil s\u00e5 att \u00e4tten dog ut. Inaveln ska ocks\u00e5 ha gjort att sp\u00e4dbarnsd\u00f6dligheten var extra h\u00f6g i sl\u00e4kten. Nio av elva br\u00f6llop under \u00e4ttens tv\u00e5hundra \u00e5r vid makten stod mellan n\u00e4ra sl\u00e4ktingar. Tv\u00e5 g\u00e5nger gifte sig farbror och brorsdotter.<\/p>\n
