30 Questions
If a population is in Hardy-Weinberg Equilibrium, what can be inferred about its genetic structure?
It is not evolving at the particular genetic locus.
What is the definition of evolution from a population genetics perspective?
A change in the genetic structure of a population over time.
In a population, if the frequency of AA homozygotes is not equal to p2, what can be concluded?
The population is not in Hardy-Weinberg Equilibrium.
What is the summation of the Hardy-Weinberg Theorem?
p2 + 2pq + q2 = 1
What does a deviation from Hardy-Weinberg Equilibrium indicate?
Microevolution is occurring.
What is the condition for a population to be in Hardy-Weinberg Equilibrium?
The frequency of AA homozygotes is equal to p2, the frequency of Aa heterozygotes is equal to 2pq, and the frequency of aa homozygotes is equal to q2.
What is the frequency of the A allele in the given population?
0.8
What is the genotype frequency of the AA genotype in the given population?
0.64
What is the condition for the Hardy-Weinberg Principle to be applicable?
Random mating and no genetic drift
What is the result of the cross between an A pollen and an a ovum?
Aa genotype
What is the equation that describes the genetic structure of a non-evolving population?
p2 + 2pq + q2 = 1
What is the name of the principle that describes the genetic structure of a non-evolving population?
The Hardy-Weinberg Principle
What is the frequency of the RP allele in Tristan da Cunha compared to Britain?
Higher in Tristan da Cunha
What is the result of gene flow between two populations?
Genetic differences between populations decrease
What is the result of the pink flowered plants being 'fitter' than the white flowered plants at the phenotypic level?
The frequency of pink flowered plants will increase
What is required for a population to be in Hardy-Weinberg Equilibrium?
A closed system with no gene flow
What happens to the frequency of the A allele and the a allele in the population over time?
The frequency of the A allele increases, and the frequency of the a allele decreases
What is the result of genetic drift in a population?
Decreased genetic variation
What is the term for the exchange of alleles between populations?
Gene flow
What is the result of the process described in the population?
Microevolution via natural selection and adaptation to the environment
What is the reason for the increase in the frequency of the pink allele (A allele) in the population?
The A allele is advantageous over the a allele
What can be affected by inbreeding in a population?
All of the above
What is the effect of natural selection on the allele frequencies in the population?
The frequency of the A allele increases, and the frequency of the a allele decreases
What is the result of the population being fixed for the white allele (a allele) in Generation 1?
The frequency of the A allele is 0.0, and the frequency of the a allele is 1.0
What is the primary source of genetic variation in a population?
Mutation
What happens to the frequency of the a allele when a mutation occurs in a white-flowered plant population?
It decreases
What is the outcome of the presence of pink flowers in a wildflower population in terms of adaptation?
They are more visible to pollen-collecting bees
What is the result of a mutation in a population in terms of genetic structure?
An alteration of the genetic structure by creating new alleles
What is the effect of natural selection on the wildflower population?
It favors the pink-flowered plants
What is the frequency of the a allele in the initial generation?
1.0
