When individuals of move into or leave a population it is called ____
A
Mutation
B
Gene Flow
C
Genetic Drift
D
Sexual Selection
Explanation: 

Detailed explanation-1: -Gene flow is the movement of genes into or out of a population. Such movement may be due to migration of individual organisms that reproduce in their new populations, or to the movement of gametes (e.g., as a consequence of pollen transfer among plants).

Detailed explanation-2: -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.

Detailed explanation-3: -Gene flow is the movement of genes into or out of a population. This may involve immigration (when new individuals enter the population) and emigration (when individuals leave the population).

Detailed explanation-4: -Emigration happens when genetically unique organisms leave one population for another. It is another form of gene flow, but it usually results in decreased genetic diversity. This is because rare alleles leave the existing gene pool.

Detailed explanation-5: -Gene flow within a population can increase the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.
