explain the concept of genetic drift to a layperson.
user
genetic drift is a phenomenon in which genetic variation within a population is reduced due to a random sampling of individuals. this random sampling can occur in a wide range of situations, but its most common occurrence is when a population is small in size or isolated. over time, this can result in changes in the genetic makeup of a population, as certain genes become either more or less common. this has important implications for the diversity and health of populations.
