Evolution and Phenotypes.
Yes, absolutely. That's what a phenotype is (definition from the biology online dictionary):


  noun, plural: phenotypes
  
  (1) The physical appearance or biochemical characteristic of an
  organism as a result of the interaction of its genotype and the
  environment.
  
  (2) The expression of a particular trait, for example, skin color,
  height, behavior, etc., according to the individual’s genetic makeup
  and environment.


I don't see anything strange in the sentence you quoted. It is phenotypes that are selected for. Genotype differences that don't affect phenotype will have no selective advantage (or disadvantage) and cannot be acted upon by evolutionary forces. What else would you use when discussing evolutionary changes? That's what the word phenotype is for.
