Proper inferences from heritability values A genetics resear

Proper inferences from heritability values. A genetics researcher determines the broad-sense heritability among undergraduates at Central Washington University to be 0.90. Which of the following conclusions/inferences could correctly be made from this result? Because Sally is a CWU undergraduate, 10% of her height is determined by non-genetic factors. Because the heritability in height among CWU students is so high, any change in the (future) students\' environment is unlikely to change the height of the (future) students. Ten percent of the variation in height among CWU students is due to variation in environmental factors. Ninety percent of the height of CWU students is determined by genes. Ninety percent of the variation in height among all the undergraduate students in the United States is due to genetic differences.

Solution

About 80 % of the height in a population is determined by genetic factors, whereas 20 % can be ascribed to environmental effects, chiefly nutrition. so most apropriat answer is thierd.
