Question

For a trait that has a genetic variance of 15 and an environmental variance of 85, the broad-sense heritability is 15 7 85 1 For a population of individuals who are genetically identical, the phenotypic variance (Vp) is the same as the genetic variance (Vg). True False If the broad-sense heritability for a trait is 1, this means that all of the phenotypic variance is due to variation in the environment. True False For a particular trait, the value for heritability is specific to a defined population in a given environment; therefore, it is possible to get two different measures of heritability for two different populations. True False Even when heritability is high, it is possible for environmental factors to influence a characteristic. True False
