Gene flow migration description
WebJun 17, 2024 · Explanation: To acquire the Hardy Weinberg equilibrium in the specified population, it must be kept in check for the random mating as given in the option. Other conditions are to have a large population which are free to mate and breed. Then there must be no allelic change in frequency as a result of mutation and mutation is allowed. Web2.3.3 Gene Flow and Introduction of Genetic Diversity. Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.
