Microevolution refers to changes that occur within a single species or group or organisms. Microevolution, as opposed to macroevolution, occurs in a short period of time. In microevolution, the ancestor and the descendant obviously belong to the same type. For example, certain pests have evolved in such a way that they become immune to pesticides; the same thing has happened to certain weeds and herbicides. Hope this helps.
Microevolution
is the changes in allele frequencies that occur over time within a
population. This change is due to four different processes which are
presented below:
The
five agents of microevolution are:
Mutations
Gene
Flow
Genetic
Drift
Sexual
Selection
Natural
Selection
The
correct answer choice is: A) It is a change in allele frequency
within a population.
Population bottlenecks. but their genes still carry the marks of this bottleneck: they have much less genetic variation than a population of southern elephant seals that was not so intensely hunted.
Cohesion is water sticking to water. adhesion is water sticking to another thing, think of it as you're adding something to the water molecules. add-hesion
