BGYB51H3 Lecture 16 Notes
-accurate measurable amount of heritability involves controlling environments, which is a
problem
-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
-heritability is specific to a particular population in a particular environment
-even if additive variation is fixed, environment variation can change and cause heritability
changes as well
-heritability always say that differences between populations is due to genetics
