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
