Question

Quizplus · Accepted Answer

The maximum value for heritability is +1.0 or 100%. This means that all of the variation in a trait within a population is due to genetic differences between individuals, and none is due to environmental differences. Negative heritability values are not possible as they would indicate that individuals with higher genetic potential have lower trait values, which is contradictory. Values greater than +1.0 are also not possible as they would imply that genetic differences can explain more than 100% of the variation, which is not mathematically or biologically plausible. A heritability value of 0.0 indicates that all trait variation is due to environmental differences, while a heritability value between 0.0 and 1.0 indicates that both genetic and environmental factors contribute to the variation.
