Which mechanism of evolution involves changes in allele frequencies caused by chance occurrences?

• Natural selection

• Genetic drift

• Mutations

• Gene flow

A drastic reduction in the size of a population that can change allele frequencies is called

• the bottleneck effect

• the founder effect

• the gene flow effect

• the Thanos effect

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection

• Variation

• Homeostasis

• Extinction

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

NGSS.HS-LS4-4

This is a pattern of natural selection in which the average (or intermediate) form of a trait is the most advantageous, and so a population evolves away from the extremes and toward the average

• Disruptive selection

• Directional selection

• Stabilizing selection

• Middle selection

This is the process that ultimately creates new variations and changes in DNA; leads to the creation of new alleles

• Mutation

• Microevolution

• Natural selection

• Gene flow / genetic drift

Tags

NGSS.HS-LS3-2

This is one of the mechanisms of evolution; it is a continuous process in which organisms with traits that make them better-adapted to their environment are more likely to survive and reproduce than organisms without such adaptations

• Directional selection

• Microevolution

• Gene flow / genetic drift

• Natural selection
