Positive selection and relaxation of purifying constraints after duplication events have driven the functional diversification of gene families involved in development. One example of this occurred within the plant MADS-box genes. The evolution of the orchid flower was driven by duplication events followed by sub- and neo-functionalization of class B DEF… CONTINUE READING
