A) low because of the relatively small differences in their environmental settings.
B) low because of the relatively large differences in their environmental settings.
C) high because of the relatively small differences in their environmental settings.

Question

Quizplus · Accepted Answer

The heritability of intelligence is affected by both genetic and environmental factors. When the environmental settings of children of less-educated parents vary greatly, it is likely that genetic differences will have less of an impact on intelligence than environmental differences. Therefore, the heritability of intelligence among children of less-educated parents is relatively low because of the relatively large differences in their environmental settings.
