To explain how cells become specialized through
differential gene expression, producing active
mRNA leading to synthesis of proteins which in
turn control cell processes or determine cell
structure in animals and plants

To explain how some phenotypes are affected by
alleles at many loci as well as the environment and
how this can give rise to phenotypes that show
continuous variation
To explain how phenotype is the result of an
interaction between genotype and the environment,
but the data on the relative contributions of genes
and environment is often difficult to interpret
