Hierarchical analysis of molecular variance (AMOVA) between human and environmental sources of Giardia duodenalis
| Gene | df | Sum of squares | Components of variance | Percentage of variation | p‐value | Fixation index | Significant FST | |
|---|---|---|---|---|---|---|---|---|
| Genetic assemblage A HC + DC) × ENV | ||||||||
