In a forest, trees that grow taller receive more sunlight and end up producing more viable seeds. Shorter trees of the same species receive less sunlight and produce few viable seeds. Over time, what type of selection will take place? directional selection stabilizing selection sexual selection disruptive selection

What effect does stabilizing selection have on a population? The average population moves toward one extreme. There is more genetic variability. The average population favors both extremes. There is less genetic variability.
Which of the following is a TRUE statement? Non-random mating will increase the number of heterozygotes. Genetic drift within a population will increase genetic variation. Migration into the population will decrease genetic variation. Mutation will decrease genetic variation. Stabilizing selection will increase genetic variation.
Hutchinson-Gilford syndrome, is an extremely rare, progressive genetic disorder that causes children to age rapidly. Under which category does it best fit? Antagonistic pleiotropy Positive selection Selection shadow All of the above None of the above
Genetic drift differs from gene flow in that Group of answer choices genetic drift occurs at a steady, but low, rate in all populations while gene flow is largely random event occurring in small populations. genetic drift is most likely to produce a loss of genetic diversity in a population whereas gene flow will often increase genetic diversity in a population. none of these choices adequately describe the difference between genetic drift and gene flow. genetic drift is based on female choice of particular mates but gene flow is largely a product of natural selection.
What is the source of new alleles within a population? mutation sexual reproduction independent assortment natural selection
Another way to say "Natural Selection" is: differential success in reproduction mutation selective breeding differential access to mating partners variation O preferential sex choices
In a population that had mice ranging in color from very light to very dark, which type of selection would result in a population of mostly dark mice? Group of answer choices Directional selection Disruptive selection Stabilizing selection
In a population of frogs, individuals with green coloration are camouflaged on leaves and are less likely to be eaten by predators. However, as the number of green frogs increases, predators learn to search for them more effectively, making it advantageous to be a less common color. What type of selection is occurring in this scenario? Disruptive selection 8888 Positive frequency-dependent selection Stabilizing selection Negative frequency-dependent selection Directional selection
Which of the following are factors that can impact genetic variation in a population? (Select all that apply.) Lack of natural selection Random mating Mutation | Migration
Which type of selection best describes the shift in peppered moth from the light form to the dark form following the industrial revolution? Directional Stabilizing Disruptive 58
Both Charles Darwin and Alfred Russel Wallace acknowledged the influence of the economist Thomas Malthus in the development of their ideas about natural selection. Specifically, Malthus's ideas about geometric population growth implied that: only the largest and strongest individuals would survive survival of the fittest resources in every generation would be limited organisms should have as many offspring as possible organisms should have a few, very fit offspring who can compete for scarce resources
Selection at one locus acts to locally maximize mean population fitness if: The population size is constant Selection is frequency independent The population is increasing in size Selection is frequency dependent The marginal fitness values are equal
