In a population of rock pocket mice living on light-colored sandy soil, the frequency of a dominant allele for dark fur color is 0.01 . Following a large-scale volcanic eruption that covers the habitat in dark basaltic rock, which of the following is the most likely prediction for the population after many generations of stabilizing environmental conditions?

The frequency of the dark fur allele will increase significantly as mice with dark fur have a higher survival rate from predators on the new substrate.

The frequency of the dark fur allele will decrease because the mutation is no longer needed once the environment becomes stable.

The dark fur allele will disappear entirely due to genetic drift because the population size likely decreased during the eruption.

The frequency of the dark fur allele will remain at 0.01 because volcanic eruptions do not cause new mutations to occur.

A population of alpine plants shows a range of flowering times. Due to global climate change, spring temperatures in the region have increased, causing snowmelt to occur three weeks earlier than historical averages. If pollinators also emerge earlier in response to the warmth, how will the allelic frequencies associated with flowering time likely change over several generations?

Alleles associated with early flowering will increase in frequency due to directional selection.

Alleles associated with late flowering will increase in frequency to avoid the erratic early spring weather.

The population will experience diversifying selection, increasing the frequency of both very early and very late flowering alleles.

Allele frequencies will remain constant because flowering time is an acquired characteristic not subject to evolution.

In a specific environment, a population of plants has two alleles for leaf pubescence (hairiness): H (hairy) and h (smooth). Hairy leaves provide resistance against a specific insect herbivore. If a new pesticide is introduced that eliminates this insect herbivore from the environment, what is the most likely long-term impact on the allele frequencies if producing leaf hairs is energetically costly to the plant?

The frequency of the h allele will increase because smooth-leaved plants no longer face herbivory and can redirect energy toward growth and reproduction.

The frequency of the h allele will decrease because the lack of competition will allow the more complex hairy phenotype to flourish.

The frequency of both alleles will remain in Hardy-Weinberg equilibrium because the agent of selection has been removed.

The frequency of the H allele will increase to 1.0 because dominant alleles always eventually reach fixation.

A population of birds experiences a severe and prolonged drought that reduces the availability of small, soft seeds, leaving only large, hard-shelled seeds as a food source. If beak depth is a heritable trait where larger beaks are better at cracking hard seeds, which of the following best predicts the change in the frequency of alleles associated with large beak depth?

The frequency of alleles for large beak depth will increase because individuals with larger beaks have a higher survival rate and reproductive success during the drought.

The allele frequencies will remain unchanged because natural selection only affects the phenotype of the current generation and not the underlying genotype.

The frequency of alleles for small beak depth will increase as the birds evolve new behaviors to utilize the hard-shelled seeds without cracking them.

The frequency of alleles for large beak depth will decrease because larger beaks require more calcium to develop, which is scarce during droughts.

An isolated population of beetles displays a phenotypic spectrum of shell thickness, controlled by multiple alleles. A new predatory bird species is introduced to the island that can easily crush thin-shelled beetles but struggles to break medium or thick shells. However, beetles with the thickest shells are significantly slower and are more frequently caught by a parasitic wasp that lays eggs in their joints. What is the most likely impact on the allele frequencies in this beetle population over time?

The population will undergo stabilizing selection, increasing the frequency of alleles that contribute to an intermediate shell thickness.

The allele frequencies will change randomly through genetic drift because the two different predators cancel out each other's selective pressures.

The population will undergo diversifying selection, where both very thin and very thick shell alleles become more common.

The population will undergo directional selection, favoring the alleles for the thickest possible shells to ensure protection from the birds.

An industrial pollutant is introduced into a river system, making the water significantly more turbid (cloudy). In a population of fish, a specific allele T codes for an enhanced lateral line system that allows for better navigation and prey detection in low-visibility water, while allele t codes for a standard lateral line system. If the T allele was previously rare due to its high metabolic cost, what is the most likely prediction for the allele frequencies after several generations in the turbid environment?

The frequency of the T allele will increase because the fitness benefit of improved navigation in turbid water outweighs the metabolic cost.

The allele frequencies will remain unchanged because the change in water clarity is an abiotic factor that does not influence biological fitness.

The frequency of the t allele will increase because it represents the ancestral, 'wild-type' state of the population.

The frequency of the T allele will decrease to 0 as the metabolic cost becomes too high in a polluted, resource-poor environment.

In a population of soil bacteria, the R allele confers resistance to a specific antibiotic, while the r allele confers sensitivity. If the environment is contaminated with this antibiotic for several years and then the contamination is completely removed, what is the most likely change in allele frequencies over time, assuming the R allele carries a significant metabolic cost in the absence of the drug?

The frequency of the r allele will increase after the antibiotic is removed because sensitive bacteria can dedicate more energy to growth and fission than resistant bacteria.

The allele frequencies will stay in Hardy-Weinberg equilibrium because the removal of a selective pressure prevents any further evolution from occurring.

The frequency of the R allele will continue to increase due to the genetic memory of the previous environmental stress.

The frequency of the R allele will remain at 1.0 because once a population evolves resistance, it cannot revert to a sensitive state.

In a hypothetical population of lizards, the allele G results in green skin, which provides camouflage in the lush rainforest canopy, while the recessive allele g results in brown skin. If a prolonged period of drought causes the rainforest canopy to thin and many trees to die, leaving a landscape of brown leaf litter and bare branches, what is the most likely impact on the allele frequencies after several generations?

The frequency of the g allele will increase because brown-skinned lizards have a selective advantage in the altered environment.

The frequency of the g allele will decrease because the drought will cause more mutations to occur in the green-skin gene.

The frequency of the G allele will increase because it is the dominant allele and will naturally mask the g phenotype.

The allele frequencies will remain in Hardy-Weinberg equilibrium because the change in vegetation is an abiotic factor.

In a certain species of flowering plant, the allele F (fuzzy seeds) is dominant over the allele f (smooth seeds). Fuzzy seeds are easily dispersed by sticking to the fur of passing mammals, while smooth seeds fall directly to the ground. If a local mammalian population goes extinct due to an emerging disease, and the plant population becomes very dense with high seedling competition, what is the most likely impact on the allele frequencies after several generations?

The frequency of the f allele will increase because producing fuzzy seed coats is an energetic waste if there are no mammals to disperse them, and smooth seeds thrive in the maternal environment.

The frequency of the F allele will increase because dominant alleles always stabilize in frequency when a selective pressure is removed.

The frequency of the F allele will reach 1.0 as the plants attempt to compensate for the lack of mammals by producing more 'sticky' seeds.

The allele frequencies will remain in Hardy-Weinberg equilibrium because the extinction of a consumer does not constitute an environmental change for a producer.

In a population of soil-dwelling invertebrates, the C allele results in a dark body color, while the c allele results in a light body color. Historically, a thick layer of dark-brown leaf litter covered the forest floor. Following an invasive fungal outbreak that kills the trees, the forest floor becomes covered in light-colored dead wood and dried moss. Which of the following best predicts the change in allele frequencies after several generations?

The frequency of the c allele will increase because light-colored individuals are better camouflaged from avian predators on the new substrate.

The frequency of the c allele will decrease because light-colored individuals are more susceptible to UV radiation in the now-open forest canopy.

The allele frequencies will remain constant because the change in substrate color is a density-independent factor that does not affect differential reproductive success.

The frequency of the C allele will increase because dominant alleles always become more common when a population faces environmental stress.
