| As polygenically inherited resistance is more stable, utilization of this type of resistance is likely to provide much more durable control of blackleg. |
| The genes involved could act with varying degrees of penetrance, or polygenically contribute to disease vulnerability with no single gene being wholly responsible. |
| Quantitative trait loci analyses have recently been initiated to map some of these polygenically controlled traits. |
| Bone density is suggested to be multifactorially regulated and polygenically determined. |
