Essential Knowledge 1.A.3

Evolutionary change is also driven by random processes.

Genetic drift is a nonselective process occurring in a small population.

Reduction of genetic variation in a given population can increase the differences between populations of the same species.

Students should be able to do:

LO 1.6 Use data from mathematical models based on the Hardy-Weinberg equilibrium to analyze genetic drift and effects of selection in the evolution of specific populations.

LO 1.7 Justify data from mathematical models based on the Hardy-Weinberg equilibrium to analyze genetic drift and the effects of selection in the evolution of specific populations.

LO 1.8 Make predictions about the effects of genetic drift, migration and artificial selection on the genetic makeup of a population.
