Demography and Populations

Introduction

Population genetic variation

Phenotypic analysis of randomly amplified polymorphic DNA markers sampled from four isolated wild populations in Argentina revealed that over 94% of total observed molecular variance was due to differences within populations, and only 6% due to differences between separate populations. Recent population fragmentation and isolation may have contributed to genetic drift and inbreeding, increasing local genetic variation and decreasing variation within populations (Bouzat 2001).
