title: Homology and concerted evolution at the alpha 1 and alpha 2 loci of human alpha-globin.
abstract: The identical structure of two racially distinct alpha 1-globin alleles and the high degree of homology between the alpha 1- and alpha 2-globin loci indicate that mechanisms exist for suppression of allelic polymorphisms and for exchange of genetic information within the alpha-globin gene complex.
