Trait: Any detectable phenotypic property or character Qualitative trait: A genetic disease trait that either present or absent. The pattern of inheritance for a qualitative trait is typically monogenetic, which means that the trait is only influenced by a single gene Quantitative trait: are measurable characteristics such as height, blood pressure, serum cholesterol, and body mass index. a quantitative trait shows continued variation under the influence of many different genes• Trait: Any detectable phenotypic property or character. • Qualitative trait: A genetic disease trait that either present or absent.
