large molecules that are typically formed by polymerization
What is macromolecule
100
This concept allows researchers to determine which individuals are contributing additional offspring to the next generation, and thus, how the population might evolve
What is relative fitness
100
_______ is the fraction of phenotype variation that can be attributed to genetic differences, or genetic variance, among individuals in a population.
What is Heritability
100
a field of study known as _______ ______ began to study how selective forces change a population through changes in allele and genotypic frequencies.
What is population genetics
100
_____ is when a few members of a species move to a new geographical area, and _____ is when a natural situation arises to physically divide organisms.
What is Dispersal vicariance
200
_______ and ________ biological processes at the molecular and chemical level, including interactions among molecules such as DNA, RNA, and proteins
What is molecular biology biochemistry study
200
Which type of selection results in greater genetic variance in a population?
What is diversifying selection
200
gradual geographic variation across an ecological gradient
What is cline
200
describes how evolutionary processes, such as natural selection, can affect a population’s genetic makeup, and, in turn, how this can result in the gradual evolution of populations and species.
What is modern synthesis
200
individuals who have two or more complete sets of chromosomes from its own species in a condition iscalled
What is autopolyploidy
300
Explain why the statement that a monkey is more evolved than a mouse is incorrect.
What is The statement implies that there is a goal to evolution and that the monkey represents greater progress to that goal than the mouse. Both species are likely to be well adapted to their particular environments, which is the outcome of natural selection.
300
favors phenotypes that are either common (____________) or rare (_______________)
What is frequency dependent -positive frequency-dependent selection -negative frequency-dependent selection
300
Do you think genetic drift would happen more quickly on an island or on the mainland?
What is Genetic drift is likely to occur more rapidly on an island where smaller populations are expected to occur.
300
Populations in nature are constantly changing in genetic makeup due to drift, mutation, possibly migration, and selection. As a result, the only way to determine the exact distribution of phenotypes in a population is
What is to go out and count them
300
an allopolyploid occurs when gametes from two different species
What is combine
400
Why do scientists consider vestigial structures evidence for evolution?
What is Vestigial structures are considered evidence for evolution because most structures do not exist in an organism without serving some function either presently or in the past. A vestigial structure indicates a past form or function that has since changed, but the structure remains present because it had a function in the ancestor.
400
states that males develop these impressive ornaments to show off their efficient metabolism or their ability to fight disease
What is the good gene hypothesis
400
Which 2 of the 5 evolutionary forces can introduce new genetic variation into a population?
What is mutations and gene flow
400
What is the difference between micro- and macroevolution?
What is Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time.
400
Which is most likely to survive, offspring with 2n+1 chromosomes or offspring with 2n-1 chromosomes?
What is Which is most likely to survive, offspring with 2n+1 chromosomes or offspring with 2n-1 chromosomes?
500
How does the scientific meaning of “theory” differ from the common vernacular meaning?
What is In science, a theory is a thoroughly tested and verified set of explanations for a body of observations of nature. It is the strongest form of knowledge in science. In contrast, a theory in common vernacular can mean a guess or speculation about something, meaning that the knowledge implied by the theory is very weak.

In recent years, factories have become cleaner, and less soot is released into the environment. What impact do you think this has had on the distribution of moth color in the population?
What is Moths have shifted to a lighter color.
500
an individual’s preference to mate with partners who are phenotypically similar to themselves.
What is assortative mating
500
In plants, violet flower color (V) is dominant over white (v). If p=.8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV), heterozygous (Vv), and homozygous recessive (vv)? How many plants would you expect to have violet flowers, and how many would have white flowers?
What is The expected distribution is 320 VV, 160Vv, and 20 vv plants. Plants with VV or Vv genotypes would have violet flowers, and plants with the vv genotype would have white flowers, so a total of 480 plants would be expected to have violet flowers, and 20 plants would have white flowers.

In the ______ ______ model, a new species undergoes changes quickly from the parent species, and then remains largely unchanged for long periods of time afterward
