Examples

  • We now know that genes modulate biological processes rather than features or traits by themselves, and that the phenotype is the net result of many processes.

    David Anderson on Creation and Evolution 2009

  • This explanation seems unlikely to us because the Cit+ phenotype is characteristic of the entire species, one that is very diverse and therefore very old.

  • On the other hand, the metabolically normal obese phenotype, is exemplified by numerous small and functional adipocytes, and thus a normal metabolic profile, despite a high BMI.

  • Daniel Smith: I believe this type of contingency therefore, to be a necessary condition for any change in phenotype requiring more than rudimentary changes genetically, (more than single point mutations certainly), IF, (and that's a big "IF"), those changes occur via the Darwinian mechanism.

  • The expression of genes is called the phenotype, and it is influenced by a host of different factors, many of them environmental.

    The Chemistry of Calm M.D. Henry Emmons 2010

  • A phenotype is what a set of genes make: a whole living creature.

  • Perhaps not NDS specifically, but "modern evolutionary theory," "standard model of evolution" and whatever else you want to call it has always assumed evolution proceeds by incremental small changes in phenotype by virtue of the relative success of certain minor variations.

    Approaching Difference, Not Likeness 2007

  • The cause and effect relationship between genes and phenotype is observable.

  • A phenotype is what a set of genes make: a whole living creature.
