Bites from infected mosquitoes
Together, all of the alleles contained within a group of interbreeding individuals is known as a
Hardy-Weinberg equilibrium assumes
No gene flow, mutation, or natural selection
In certain species of nonhuman primates there are groups where only one dominant female has female has access to mates. The other females must wait until the opportunity to gain mate access presents itself. This will have direct impacts on "fitness," influencing which of the following?
Another name for the evolutionary force called gene flow is
Australian aborigines are an endogamous society. This means that marriage and reproductive take place within the group, leading to
Decreased genetic diversity due to a lack of admixture
A point of mutation that does not result in a change to the amino acid codes for is said to be a
Over a period of two generations, the frequency of green dung beetles in a population shifts from 75% to 71% while the frequency of brown dung beetles within this population shifts from 25% to 29%. This is an example of
Spontaneous mutation is the result of
The evolution of the modern horse with a single hoof on each limb from a dog-sized ancestor with multiple digits is an example of
bites from infected mosquitos.
Together, all of the allele contained within a group of interbreeding individuals are known as a:
The physical location of a gene within the genome is called the:
Evolution can best be defined as:
a process that occurs only over extremely long periods of time.
When individuals of the same species are reproductively isolated, genetic differences may accumulate in sufficient number so that new species could, emerge. Such an event would be an example of:
The ABO and MN blood-type frequencies of the Dunkers differ significantly from those of current American and German populations due to:
Australian aborigines are an endogamous society. This means that marriage and reproduction take place within the group, leading to:
decreased genetic diversity due to a lack of admixture
Transposable elements are DNA sequences that:
can copy themselves into entirely new areas of the chromosomes.
Studies of Galapagos finches have found that at certain points in time all finches on the island have either wide beaks or sharp narrow beaks. The type of evolution that leads to this phenotype distribution is ______ selection.
Patrilocal societies are expected to display:
greater mtDNA diversity than Y chromosome diversity.
The evolution of the modern horse with a single hoof on each limb from a dog-sized ancestral species with multiple digits is an example of:
An individual who displays the disease sickle-cell anemia must have inherited the deleterious allele from both phenotypically normal parents. This individual is therefore:
homozygous, with two recessive alleles.
The type of selection that favored progressively larger brain size in human evolution is ____ selection.
The clinal decrease in type B blood from East Asia to Western Europe is probably the result of:
Mutations in DNA found in which cells are most likely to have significant evolutionary consequences?
Sex cells (gametes) ( ͡° ͜ʖ ͡°)
You are reading a scientific article about cheetahs that have stripes instead of spots. the article refers to this as a genetic mutation. Though you see they have no negative impact on the cheetah's fitness, the stripes are nevertheless considered a genetic mutation because mutations:
can result in an evolutionary advantage/ disadvantage and may have no effect on the phenotype ; all of the above
The best-documented case of industrial melanism involves:
What effect does natural selection have on population variation?
The mutation known as trisomy 21. in which an extra copy of chromosome 21 is present, is more commonly known as _____ syndrome.
Together, all of the alleles contained within a group of interbreeding individuals is known as a:
Fitness trade-off refers to selection favoring which genotype?
While conducting research with a small population in South America you note that an overwhelming majority of individuals exhibit signs of a specific genetic abnormality. This is most likely the result of:
Evolution can best be defined as:
a change in allele frequencies in a breeding population over time.
When individuals of the same species are reproductively isolated, genetic differences may accumulate in sufficient number so that new species could emerge. Such an event would be an example of:
Another name for the evolutionary force called gene flow is:
Australian aborigines are an endogamous society. This means that marriage and reproduction take place within the group, leading to:
decreased genetic diversity due to a lack of admixture
What effect does natural selection have on population variation?
The vector for transmitting the malarial parasite to humans is:
The evolution of the modern horse with a single hoof on each limb from a dog-sized ancestor with multiple digits is an example of:
showed that U.S.-born children had different head shapes than their immigrant parents.
is advantageous because it provides protection from solar radiation
Johann Friedrich Blumenbach:
categorized skulls into five racial types
R.C. Lewontin found that human “races” have no taxonomic significance. He demonstrated this:
through research indicating that most genetic variation is found across human populations
The prenatal stage in humans consists of:
Allen’s rule indicates that humans will have:
longer limbs in hot environments and shorter limbs in cold environments.
Sexual maturation or puberty is marked by:
David Barker’s research on poor early health led to the hypothesis that:
poor health during the fetal period results in the reduced ability to maintain homeostasis.
The obesity pandemic is due to:
the increased ability to produce and consume inexpensive, high-fat foods
The maintenance of homeostasis
involves all levels of any organism’s biology.
The increased brain size observed in the order Primates:
results in extended periods of nursing and development to accommodate increasing behavioral complexity and demonstrates the importance of intelligence in primate evolution.
Modern primates are characterized by arboreal adaptations, including:
Primates are characterized by:
arboreal adaptation, dietary plasticity, and parental investment
give birth to fewer offspring than do many other mammals
The genetic classification for apes and humans:
includes three subfamilies within hominids: pongines, gorillines, and hominines
Relative to other primates, prosimian adaptations include:
an enlarged olfactory bulb and enlarged scent glands.
While observing primates at the zoo, you notice that the particular monkey you are watching uses its hands, feet, and tail to move throughout the trees in its enclosure. This is most likely:
a New World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet
The typical catarrhine dental formula is:
A feature unique to human teeth and human ancestors’ teeth is:
a canine that shows wear on the tip.
a wet nose, a snout, a tooth comb, and a grooming claw.
