Practice question · Multiple choice
A child with a genetic tendency toward reading ability is read to more, chooses more books, and is put in a better class. Why does this make heritability and environment hard to separate?
Hints
- Ask who chose the bookshelf, and why the parents bought it.
- The child's tendency is causing the environment. What does that do to the partition?

D. Because the genotype is helping to select the environment
Why
The genotype is not sitting in a randomly assigned environment, it is helping to choose one, evoking responses and selecting niches. So a share of what the estimate books as environment was set in motion by genes, and the clean split between nature and nurture never quite exists to be measured.
