Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	nonrandom mating
B	geographic isolation
C	genetic drift
D	gene flow

Explanation:

Detailed explanation-1: -The effect of gene flow is to reduce genetic differences between populations, thereby preventing or delaying the evolution of the populations in different geographical areas into separate species of the pathogen.

Detailed explanation-2: -Animals experience gene flow when individuals leave a family group or herd to join other populations. The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population.

Detailed explanation-3: -Genetic drift is the change in allele frequencies in a population over time due to random sampling events (e.g., differences among individuals in survival or fecundity that are unrelated to their phenotype/genotype).

Detailed explanation-4: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.
