True or False: Microevolution is commonly observed in real-time
The magnification of genetic drift as a result of natural events or catastrophes is _____; _____ is the flow of alleles in and out of a population due to the migration of individuals or gametes.
In a species of water snake has populations on the mainland and on an island, snakes are regularly washed from the mainland to the island where they become part of the breeding population on the island. For the island population, this violates the assumption of ______________________ because the evolutionary mechanism of________________ is present.

- please answer all parts with good explanation and clear answerarrow_forwardTrue or False If a population is in H-W equilibrium, then all the alleles in the population have the same frequencies.arrow_forwardUse the following additional passage to answer the next question. Suppose you travel to the future, to a time when neither cystic fibrosis nor tuberculosis have caused any deaths for many generations. In all of these future populations, the cystic fibrosis allele still exists at a low frequency. Q10. You visit a huge city with millions of people. If you were to start sampling the cystic fibrosis allele from one generation to the next, what should happen to its frequency over the next few generations, and why? O The allele frequency should change a lot from one generation to the next due to random genetic drift. O The allele frequency should not change much from one generation to the next because the population is large. O The allele frequency should steadily increase due to natural selection. O The allele frequency should steadily decrease due to natural selection.arrow_forward
