title: Estimating total genic diversity in the house mouse.
abstract: In a survey of variation in both electrophoretic charge and thermostability at 14 structural loci in 40 strains of Mus musculus, 27 electromorphs (polypeptides differing in electrophoretic charge) and 20 thermomorphs (polypeptides differing in thermostability) were found. Electrophoresis detected 11 new variants within thermomorphs, and the heat denaturation technique detected four new variants within electromorphs. From these data, and making the assumption that both techniques are independent of each other, it is estimated that the actual total number of alleles at the 14 loci is 53, or an average of 3.79 per locus (1.96 per electromorph), and that electrophoresis apparently detects one-third of the variants, thus describing about 50% of the alleles at structural gene loci in the house mouse.
