Reindeer from a rancher in Alaska escape from their pen during an enormous snow storm. After their escape, they mate with wild caribou that are migrating across the land. The offspring of these have traits for short legs and have tame behavior.
Gene Flow
Genetic Drift
Non-Random Mating
Natural Selection
Males of the bighorn sheep species fight one another to show females who is the dominant male and are more likely to mate with females.
Natural Selection
Mutation
Genetic Drift
Non-Random Mating
During a hurricane, a population of beetles almost gets completely wiped out. The only beetles that survived were lucky that they were in their nest at the time of the hurricane and had enough food to survive.
Natural selection
Genetic Drift
Gene Flow
Non-Random Mating
Insects become resistant to pesticides very quickly, sometime in one generation. If an insect is resistant to the chemical, most of the offspring will also be resistant. Considering that insect generations can be a matter of weeks, insects in an area can become immune to a chemical within months.

A chemical spill causes a genetic change in the offspring of ladybugs to have blue dots instead of black dots.

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
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
The Amish have a higher frequency of polydactyly (extra fingers) in their community than the general population. This is due to the allele for extra fingers being present in the group that started the Amish community.
The difference in allele frequency is due to genetic flow.
The difference in allele frequency is due to the founder effect.
The difference in allele frequency is due to a bottleneck.
The difference in allele frequency is due to speciation.

Which option is an example of Genetic Drift?
Mutation
Bottleneck Effect
Adaptation
Finders Keepers
This term refers to the total genetic information found in a population; the complete collection of all the alleles found in a population
Gene library
Genome
Gene pool
Allele pool
What is the purpose of mutations in evolution?
To change the genetic material of a cell
To increase biodiversity in a population
To cause a reduction in population size
To allow organisms to better adapt to their environment
Adaptations can be:
camouflage
ability to survive cold weather
hunting skills
all of the above
