Key Concepts Covered
➡️ Genetic drift – Random fluctuations in allele frequencies that occur by chance rather than natural selection
➡️ Bottleneck effect – Sudden reduction in population size leading to decreased genetic variation
➡️ Founder effect – Genetic variation change when a new population is established by a small number of individuals
➡️ Genetic diversity – The total number of genetic characteristics in the genetic makeup of a species
➡️ Allele fixation – When a particular allele becomes the only variant in a population, potentially due to drift
