-one strategy is ensuring offspring and parents have different environments in order to control
for environment effect (e.g. cross-fostering or reciprocal transplant)
-another strategy is ensuring all offspring have the same environment

changes as well
-heritability always say that differences between populations is due to genetics
be because of different environments)
