Two types of nomenclature have been assigned to the genes encoding the Alpha-AMY-1 isozymes. In one, allelic states are defined for individual isozymes (568) while in the other several isozymes are considered to be the products of compound loci (569, 576). This listing shows the 'alleles' described in (568) which are assumed in (576) to be synonymous with the Alpha-Amy-B1a through (Alpha-Amy-B1h nomenclature. Amy 4 and Amy 4' are unmapped alternatives (568) which appear to be identical to zymogram bands [bands 9 and 9b (576) forming part of the Alpha-Amy-B1 phenotype. Amy 6B1 [with forms Amy 6B1o, and Amy 6B141 considered to be mutually exclusive (568)]and Amy 6B2 [with forms Amy 6B2 and 6B2o (568)] described further aspects of Alpha-Amy-B1 (576). See Alpha-Amy1 below for further consid- eration of Amy 6B2 (568).
