Segregation analysis of 996 families in which the gene for beta-thalassemia was segregating showed no distortion of expected Mendelian ratios. No appreciable frequency of sporadic cases was detected. It was suggested that segregation distortion is not a mechanism which contributes to the maintenance of polymorphism in the beta-thalassemia system in the population of the Ferrara area.
对996个β地中海贫血基因发生分离的家族进行的分离分析显示,预期的孟德尔比率未出现偏差。未检测到明显的散发病例频率。有人认为,分离畸变并非费拉拉地区人群β地中海贫血系统中维持多态性的一种机制。
