Phenotypic variation that is due to genetic differences is referred to as heritability. It can be the Broad-sense heritability and Narrow-sense heritability, the Broad-sense heritability which is ranges from 0 to 1. Identify the correct prediction about these ranges?

a) 0 is all of the phenotypic variance results from differences in genotype

b) 0 is all of the phenotypic variance results from environmental variation

c) 1 is all of the phenotypic variance results from differences in genotype

d) 1 is all of the phenotypic variance results from environmental variation
