analysis of other dna markers closely linked to the beta-globin gene cluster -- segment 12 of chromosome 11 ( d11s12 ) and loci for insulin , the cellular oncogene c-ha-ras , and preproparathyroid hormone -- confirmed that a crossover event must have occurred within the region of chromosome 11 between d11s12 and the beta-globin gene cluster .
