摘　　要：对所发现的一种新的ＢＡＬＢ／ｃ突变小鼠的遗传特性，包括遗传规律、染色体组型和Ｇ带核型以及１９个生化基因部位进行了研究。该突变小鼠是由１对基因突变所致，该基因位于常染色体上，呈半显性遗传。３种表型小鼠的正常核型、Ｇ带核型以及所测定的所有生化基因部位间无明显差异，且与正常ＢＡＬＢ／ｃ小鼠的一致。Inheritance 19 gene marks ,normal karyotypes and G-bands of choromo- somes in the new mutant mice with three phenotypes (Haired,H;Sparse-coat,S;Bald- coat,B)were investigated.Mating studies showed that the mutation was caused by an autosomal semidominant gene.Among the three phenotypes,no difference was ob- served in the normal karyotypes,G bands as well as 19 gene markers examined,which were similar to those of nomal BALB/c mice.The mutation did not cause marked change in these characteristics.The location of the mutant loci should be further stud- ied.
