Intro Video: http://www.youtube.com/watch?v=znfnO2j5wf0
Multifactorial traits are traits affected by multiple genes. They are not just punnet square type problems, genes from multiple chromosomes determine the phenotype. These traits are also influenced by the environment around it.
Multifactorial traits are exactly like they sound, traits controlled by multiple factors, or in this case, traits controlled by multiple genes and the environment. Most of our traits fall into this category. They are traits that vary slightly from individual to individual, such as height and hair color as well as the common chronic conditions such as heart disease, diabetes, and cancer that we looked at in the activity What is Your Risk for Disease, with the Genomisons.
