HETEROZYGOSITY OF FOUR POPULATINONS OF BRANCHIOSTOMA BELCHERI GRAY IN XIAMEN
厦门文昌鱼(Branchiostoma belcheri Gray)种群杂合性研究

Heterozygosity of Branchiostoma belcheri Gray in Xiamen was investigated using vertical slab polyacryla-mide gel electrophoresis.Seven enzymes presumably encoded by 14 allozyme loci in B.belcheri.They are Aat-1,Amy-1,Amy-2,Amy-3,Amy-4,Me-1,Me-2,Mdh-1,Mdh-2,Sod-1,Sod-2,Est-1,Est-2,and Per-1,of which 8 loci are polymorphic,they are Sod-1,Aat-1,Me-1,Me-2,Mdh-1,Mdh-2,Est-2,Amy-2.The genotypic distribution observed at Me-1,Mdh-1 and Est-2 in all populations and Amy-2 in East of Southern line to 18 population was...
