Start each round with an empty gene pool (bowl). Population splits off or becomes isolated from the parent population. To represent the gene pool of this generation, each person should put three copies of their genotypes (six beads total) into the gene pool. Since then, their population has rebounded to over 30,000.
It occurs when a population undergoes a drastic reduction in size for at least one generation due to a catastrophic event like natural disasters (earthquakes, floods, and fires) or disease. Web genetic drift is the idea that in small populations, allele frequencies can change as a result of random selection, rather than only natural selection.
