It has long been realized that the distinction we make for
heuristic purposes between ``genotype'' and ``environment'' is an
approximation which ignores several processes that might be important
in human populations. Three factors defy the simple separation of
genetic and environmental effects, but are likely to be of potential
significance from what we know of the way genes operate in other
species, and from the logical consequences of the grouping of humans
into families of self-determining individuals who share both genes and
environment in common.
The factors we need to consider are:
Each of these will be discussed briefly.
- assortative mating
- genotype-environment covariance (CovGE, or
genotype-environment correlation, CorGE)
- genotype environment interaction (GE).
