A scientific law is formed when the results of an experiment generate the same results every time a particular experiment is performed. A scientific law is made when something has been thoroughly tested again and again through experimentation. Unlike the theory, a scientific law is not subjected to change with time.

Genetic drift is defined as a shift in the allelic frequency of a population. This can be caused by natural selection which is the differential survival and reproduction of individuals across a population due to differences in phenotype. Natural selection favors particular traits in a population hence these individuals are able to reproduce while the individuals with disadvantageous traits will pass their genes to succeeding generations. This way the allelic frequency of succeeding generation will be diferent from that of the parent population.
