60 Questions
Which of the following statements about speciation is correct?
Speciation creates new and distinct species through the process of evolution.
Which of the following is NOT a condition for Hardy-Weinberg Equilibrium?
Natural selection acts on the population, favoring certain alleles.
What is the primary source of genetic variation in a species?
Random mutations that create new alleles.
Which of the following statements about allele frequencies in real populations is FALSE?
Allele frequencies remain constant in real populations due to Hardy-Weinberg Equilibrium.
Which of the following is NOT a way in which new variation can arise in a population?
Natural selection favoring certain alleles over others.
What is the primary reason why evolution often occurs without creating new species?
Genetic changes in a population are too small to create new species.
Which of the following statements about mutations is correct?
Mutations form at random due to mistakes in DNA replication or damage.
Which of the following is a condition for Hardy-Weinberg Equilibrium?
Individuals mate randomly, and alleles are passed down randomly.
Which of the following statements about evolution is correct?
Evolution involves genetic changes in a population over time, without necessarily creating new species.
If a population experiences a steady influx of new alleles through migration, which of the following statements is true regarding Hardy-Weinberg Equilibrium?
The population will deviate from Hardy-Weinberg Equilibrium due to the violation of the assumption of no gene flow.
If a population experiences a severe bottleneck event, where only a small number of individuals survive, which of the following is most likely to occur?
The population will experience a significant reduction in genetic variation due to the random loss of alleles.
If a population experiences a selective pressure that favors a particular phenotype, which of the following statements is true regarding the allele frequencies associated with that phenotype?
The allele frequencies associated with the favored phenotype will increase over time, as natural selection favors individuals with that phenotype.
If a population experiences a high mutation rate at a particular locus, which of the following statements is true regarding the allele frequencies at that locus?
The allele frequencies will decrease for the most common allele, as mutations tend to introduce new, rare alleles.
If a population experiences strong directional selection for a particular phenotype, which of the following statements is true regarding the potential for speciation?
Speciation is more likely to occur, as directional selection can lead to the accumulation of genetic differences between populations.
If a population experiences a high rate of random mating, which of the following statements is true regarding the potential for speciation?
Speciation is less likely to occur, as random mating homogenizes genetic variation within the population.
If a population experiences a high rate of gene flow between subpopulations, which of the following statements is true regarding the potential for speciation?
Speciation is less likely to occur, as gene flow homogenizes genetic variation between subpopulations.
If a population experiences a high rate of genetic drift, which of the following statements is true regarding the potential for speciation?
Speciation is more likely to occur, as genetic drift can lead to the accumulation of genetic differences between subpopulations.
If a population experiences a high rate of sexual selection, which of the following statements is true regarding the potential for speciation?
Speciation is more likely to occur, as sexual selection can lead to the accumulation of genetic differences between subpopulations.
If a population experiences a high mutation rate at a particular locus, which of the following statements is true regarding the allele frequencies at that locus?
New alleles will be introduced, leading to changes in allele frequencies.
Which of the following statements about the Hardy-Weinberg Equilibrium is correct?
It assumes that allele frequencies remain constant in the absence of evolutionary forces.
Which of the following statements about speciation is correct?
Speciation is the process that creates new and distinct species from existing ones.
If a population experiences a steady influx of new alleles through migration, which of the following statements is true?
The population will experience an increase in genetic variation.
Which of the following statements about evolution is correct?
Evolution can occur without creating new species, through changes in allele frequencies.
If a population experiences a severe bottleneck event, where only a small number of individuals survive, which of the following is most likely to occur?
The population will experience a decrease in genetic variation.
Which of the following statements about mutations is correct?
Mutations are the original source of all alleles in a species.
Which of the following is NOT a condition for Hardy-Weinberg Equilibrium?
Individuals can freely join or leave the population.
Which of the following statements about allele frequencies in real populations is FALSE?
Allele frequencies remain constant in real populations.
What is the primary mechanism that introduces new alleles into a population?
Mutations

Which of the following statements about evolution is correct?
