Heritability May Be Calculated as Which of the Following

Question

Heritability may be calculated as which of the following?
A) the total variance minus environmental variance
B) total variance minus genetic variance
C) genetic variance divided by environmental variance
D) genetic variance divided by total variance
E) None of these choices are correct.

Accepted Answer

Heritability is calculated as the proportion of total phenotypic variation that is attributable to genetic variation. This can be calculated as the ratio of genetic variance to total variance, as heritability does not account for environmental variation. Therefore, the correct choice is D, genetic variance divided by total variance.
