Inheritance of complex traits

Complex or multifactorial traits result from a combination of multiple genetic and environmental factors (such as lifestyle choices about diet and exercise), only some of which might be known. Accordingly, no single gene or environmental factor causes a complex trait.

Many birth defects, such as cleft lip and cleft palate, as well as many adult disorders, such as heart disease and diabetes, are examples of complex traits. Many complex traits are common – generally occurring in at least 1 out of every 1000 individuals.

Predicting an individual’s risk having a complex disease (i.e., risk of occurrence) or passing on a complex disease (i.e. recurrence risk) is difficult because each risk factor (whether genetic or environmental) contributes just a small part to an individual’s overall risk.

My46 is an innovative web-based tool that enables individuals to manage their own genetic testing results.

Your genome is your entire genetic code or all of the DNA in a cell.

What My46 Means

Most human cells have 46 chromosomes that provide the genetic instructions for a body to live, grow, and develop.
