Question

When all of the variation in a population is due to environmental sources and there is no genetic variation, broad sense heritability (H2):

is zero and all of the phenotypic variability is due to loci at other locations

is zero and all of the phenotypic variability is due to environment

is some negative value indicating the phenotypic variability is due to some recessive loci

is some positive value indicating the phenotypic variability is due to some dominant loci

none

is zero and all of the phenotypic variability is due to loci at other locations

is zero and all of the phenotypic variability is due to environment

is some negative value indicating the phenotypic variability is due to some recessive loci

is some positive value indicating the phenotypic variability is due to some dominant loci

none

Explanation / Answer

When all of the variation in a population is due to environmental sources and there is no genetic variation, broad sense heritability (H2) is zero and all of the phenotypic variability is due to environment.
