The determination of dental arch forms is a multifactorial trait.
Athletic performance is a multifactorial trait, determined by a range of genetic and environmental factors.
Yield is a multifactorial trait, integrating various developmental and physiological processes.
Phenotype is a multifactorial trait that often results from the contribution of many proteins.
Longevity is a multifactorial trait with a genetic contribution, and mitochondrial DNA (mtDNA) polymorphisms were found to be involved in the phenomenon of longevity.
Human essential hypertension (EHT) is a multifactorial trait with a complex genetic basis.
Impulsivity is a multifactorial trait characterized by unplanned responding and hasty decision making that may be unduly risky or neglect negative consequences.
The large number of replicated SNPs provides further support for the hypothesis that exceptional longevity is a multifactorial trait that is determined in part by an enrichment for common genetic variants imparting protective effects [ 1, 7, 8].
The latter scenario, however, seems highly unlikely because, as far as it is known from other cave fish, aborted eye development is a multifactorial trait in which at least six genes are involved and, in addition, the lack of pigmentation is caused by different genes [ 5].
Additional factors either encoded by the virus itself or provided by the host cell significantly contribute to host restriction, transmission and pathogenicity, and therefore, influenza virulence clearly is to be regarded a multifactorial trait.
