| A conceptual framework for understanding how polygenes give rise to discrete phenotypic variation is the threshold model. |
| A second testicular metric that may correlate with reproductive potency and phenotypic condition is directional asymmetry. |
| Classical quantitative genetics has applied linear modeling to the problem of mapping genotypic to phenotypic variation. |
| Isolates underwent polyphasic analyses employing phenotypic and genotypic assays to determine species identification. |
| Recent data has shown that women can have full phenotypic expression of HH, including cirrhosis. |
| All negative strains that appeared oxacillin resistant by phenotypic methods were tested for production of beta-lactamase by iodometric method. |
