Let's say that we measure the height of every student in your class and conclude that the heritability coefficient is + .75. This means that
A)height is genetically determined
B)about 75% of height variation in the class is due to genetic factors
C)about 75% of height variation in the class is due to environmental factors
D)height in the general population is about 75% genetic
E)we made an error-heritability cannot exceed + 0.50

The heritability coefficient of +.75 indicates that approximately 75% of the variation in height within the class can be attributed to genetic factors. This does not imply that height is solely determined by genetics for any individual, nor does it apply to the general population outside the class. It specifically refers to the proportion of variation in the trait (height, in this case) that is due to genetic differences among individuals in the class.
