a trait is considered to be multifactorial in origin when two or more genes, together with an environmental effect, work together to lead to a phenotype. [Source: NHBLI/NCBI Glossary
Having many factors or causes
A phenotype caused by two or more genes.
involving or depending on several factors or causes (especially pertaining to a condition or disease resulting from the interaction of many genes)
Describes a trait that is determined by the interaction of multiple genetic and environmental factors.
Describes traits or diseases that are the result of the interaction between multiple genetic and environmental factors. A good example is heart disease.
involving many factors at the same time.
Inheritance due to multiple genes at different loci which summate and interact with environmental factors.
A characteristic influenced in its expression by many factors, both genetic and environmental.
Resulting from multiple factors interacting together.
an inheritance pattern involving both genetic and environmental factors.
Caused by the interaction of multiple genetic and environmental factors.
A trait controlled by at least two factors, which may be genetic or environmental; polygenic traits represent a subset of multifactorial traits.
Means 'many factors involved'. When used about a disease, means it has more than one cause. For example, someone may develop a cancer partly because of their genetic make up, partly because of their diet and partly because of other factors in their environment.
A pattern of inherited characteristics, such as physical traits or diseases, that results from the interaction of gene and the environment.
