Abstract excerpt
DNA analysis of the alpha-globin gene cluster showed that the frequency of the -alpha 3.7 deletion in the non-white cuban population is about 0.12, in agreement with a 47% admixture of the original African slaves introduced in the island. In the S-S homozygotes the frequency is slightly higher (.18), probably due to a selective advantage produced by the presence of alpha-thalassemia in sickle cell patients.
