Heritability is a statistical measure that describes the proportion of variation in a trait that is attributable to genetic factors. It is often expressed as a percentage or a decimal between 0 and 1. For example, if the heritability of height is 0.8, it means that 80% of the variation in height is due to genetic factors, while the remaining 20% is due to environmental factors.
