Mutation and the experimental evolution of fitness
In a lab experiment we examined the evolutionary effects
effects of genetic stress: a harmful recessive mutation (nub E and nub X)that
was experimentally introduced into a population of flies hundreds of years ago
The goals were to assess the impact of nub on juvenile fitness, the impact of
nub on adult fitness and to assess the degree of compensatory evolution in the
evolved wingless population We compared two populations with one another (nub
E and nub X) and with a base population for reference What could be wrong with
this experiment? Could other genetic mechanisms played a role in the
differentiation of these populations? If so, how could this have been made a
better experiment?
