Which of the following CANNOT affect narrow sense heritabili

Which of the following CANNOT affect narrow sense heritability of a trait? a) linkage equilibrium b) natural selection c) truncation selection d) artificial selection e) environmental effects on phenotype expression f) allele frequencies g) all of the above can affect trait heritabilities

Solution

The correct answer is \" all of the above can affect trait heritabilities\".

Narrrow sense heritability is defined as the variation in the phenotypic traits due to additive genetic effect.

all the factors mentioned above will affect the phenotype of the individual and in turn will affect the narrow sense heritability.
