n, number of individuals. Localities are indicated by numbers as in Fig. 1. Allelic designations at locus G6P, AAT or ∗∗∗ indicate the presence or absence of the AAT trinucleotide; at locus actin, + or − indicate the presence or absence of HindIII restriction site; and at locus HN49, + or − indicate the presence or absence of 14-bp insert.
