The bottleneck effect is a genetic phenomenon that occurs when a population's size is significantly reduced for at least one generation, often due to environmental events like natural disasters or human activities. This drastic reduction can lead to a loss of genetic diversity, as only a small number of individuals contribute to the future gene pool. As a result, the surviving population may exhibit reduced adaptability and increased vulnerability to extinction. Over time, the genetic characteristics of the population may diverge from the original population, leading to distinct evolutionary paths.
What else can I help you with?
What are the two types of genetic drift?
There are two types of genetic drift, there is a the population bottle neck effect and the founder effect. The population bottle neck effect is when a population greatly decreases in size due to some random ecological event and the small population has a greater chance of genetic variation. The founder effect is a variation of the bottle neck effect in which a small portion of a larger population to branch off or get "isolated" from the larger population and have a greater chance of genetic variation. Have fun and hope this helps.
