Top 10 Commonly Confused Words in Landscape Genetics

Top 10 Commonly Confused Words in Landscape Genetics 1. Gene Flow vs. Genetic Drift Gene flow and genetic drift are two fundamental processes shaping the genetic structure of populations. While both involve changes in gene frequencies, they differ in their mechanisms. Gene flow occurs when individuals migrate between populations, introducing new genetic material. On the other hand, genetic drift refers to random fluctuations in gene frequencies, often due to chance events. Understanding these processes is crucial for studying population dynamics and evolutionary patterns. 2. Isolation by Distance vs. Isolation by Barrier In landscape genetics, understanding how populations become isolated is essential. Isolation by distance occurs when the genetic similarity between populations decreases with increasing geographic distance. This can be due to limited dispersal capabilities. On the other hand, isolation by barrier refers to the genetic differentiation caused by physical barriers, such as mountains or rivers. Both types of isolation play a significant role in shaping genetic patterns across landscapes. 3. Habitat Fragmentation vs. Habitat Loss
