- 1. Multiple Choice
What does allele frequency refer to in a gene pool?
The number of genes in the pool
The number of times an allele occurs in a gene pool, compared to the total number of alleles in that pool for the same gene
The total number of alleles for all genes in the pool
The percentage of genes that are homozygous for a given allele
- 2. Multiple Choice
What is genetic drift?
A) A predictable change in allele frequency due to natural selection
B) A random change in allele frequency
C) The transfer of alleles from one population to another
D) A change in allele frequency due to mutation
- 3. Multiple Choice
In which type of populations does genetic drift usually occur?
A) Large populations with stable allele frequencies
B) Small populations
C) Populations with high mutation rates
D) Populations undergoing natural selection
- 4. Multiple Choice
What is the bottleneck effect in the context of genetic change in populations?
An increase in genetic diversity due to mutation
A change in allele frequency following a dramatic increase in the size of a population
A change in allele frequency following a dramatic reduction in the size of a population
The introduction of new alleles into a population through migration
- 5. Multiple Choice
What can cause a population's gene pool to contain different gene frequencies from the original gene pool?
Consistent population size over time
A disaster that kills many individuals in a population
Random mating within a population
No change in the environment
- 6. Multiple Choice
What occurs when allele frequencies change as a result of the migration of a small subgroup of a population?
Natural selection
Genetic drift
The bottleneck effect
The founder effect
- 7. Multiple Choice
What does the Founder Effect refer to in the context of evolution and genetic change in populations?
The effect of natural selection on a large, diverse population
The genetic drift that occurs when a new population is established by a very small number of individuals from a larger population
The increase in genetic mutations when a population size becomes too large
The process by which a new species is created from an existing species
- 8. Multiple Choice
What is a population in genetic equilibrium?
A) A population where allele frequencies change and the population evolves.
B) A population where allele frequencies in the population remain the same and the population does not evolve.
C) A population that has an excess of mutations leading to rapid evolution.
D) A population that is isolated from other populations and evolves differently.
