Variation Among Individuals That is Due to Factors Other Than

Question

Variation among individuals that is due to factors other than genetic factors is called ________.
A) phenotypic variation
B) environmental variation
C) broad-sense heritability
D) narrow-sense heritability

Accepted Answer

Environmental variation refers to differences among individuals that are caused by factors other than genetics, such as exposure to different environmental conditions or experiences. Phenotypic variation refers to any difference in observable traits among individuals, which can be caused by both genetic and environmental factors. Broad-sense heritability refers to the proportion of phenotypic variation that can be attributed to genetic factors, while narrow-sense heritability specifically refers to the fraction of phenotypic variation that is due to additive genetic effects.
