How genetic drift leads to evolution
WebThis genetic drift can lead to changes in allelic frequency in a gene pool (modification) which will then be passed on to future generations (decent). Changing the allelic frequencies of a population is evolution. Students should predict that the smaller sample size will have a greater influence.
