Many people adopt children, and studies indicate that there are similarities among adoptive families. Some researchers are concerned that these similarities will enhance genetic differences among adopted children, and thus impact the results of adoption studies. What impact may be expected by adoptive family similarity and why would this affect studies that compare environmental and genetic influences?

What will be an ideal response?


Even if a trait is highly heritable, it still interacts with the environment. If adoptive families provide very similar environments, genetic influences can be magnified. This situation would be analogous to raising genetically diverse plants in identical settings of nutrients, light and water. Any differences you see in the plants under these conditions will be mostly genetic.
