From: Genetic variation in the mitochondrial 16S ribosomal RNA gene of Ixodes scapularis (Acari: Ixodidae)
The number of mt 16S rRNA gene haplotypes ( h ) of I. scapularis found in different geographical regions of Canada, and the Midwest and Northeast of the United States. The numbers inside parentheses indicate the number of haplotypes only found exclusively in a geographical region. Also shown is the number of haplotypes (inside yellow boxes) shared among geographical regions.
