Abstract
Restriction fragment length polymorphisms of the L1.28 probe which is closely linked to X-linked disorders, retinitis pigmentosa and Norrie disease, were studied in samples from England, India and Nigeria. The frequency of the A2 allele (9-kb fragment) was 0.23, 0.55 and 0.46 in England, India and Nigeria, respectively. The differences between the English and Indian populations were highly significant.
摘要
对与X连锁疾病、色素性视网膜炎和诺里病紧密连锁的L1.28探针的限制性片段长度多态性进行了研究，研究样本来自英格兰、印度和尼日利亚。在英格兰、印度和尼日利亚，A2等位基因（9千碱基片段）的频率分别为0.23、0.55和0.46。英格兰和印度人群之间的差异非常显著。
