Which of the following is an example of natural selection?
Breeding horses, humans selecting which traits make the fastest race horses
Giraffes with the longer necks will be most likely to survive, reproduce, and pass that trait to their offspring.
Giraffes stretching their necks to reach leaves and passing that trait to their offspring.
Cropping the ears of a boxer dog
Refer to the picture. This is representing

Which of the following is an example of an adaptation?
Dog breeding, humans selecting which traits are most beneficial
Different tortoise shell shapes, depending on the food available to them.
Giraffes stretching their necks to reach leaves and passing that trait to their offspring.
Cropping the ears of a boxer dog
Refer to the picture. This is representing
Directional selection
Disruptive selection
Stabilizing selection
Artificial selection
This is the combinations of all of the genes present in a given population.
genome
allele frequency
microevolution
gene pool
Which of the following is part of Darwin's theory of evolution?
Geographic isolation will cause speciation
Organisms will create mutations that will all them to survive better
The organisms that can adapt best to their environment will survive
Natural Selection is caused by a natural disaster
Then a tiger and a lion mate, they create a liger. The tiger and lion are not the same species because:
The liger is not able to adapt to its environment
The liger does not live long after it is born
The liger is not a real animal
The liger is not able to reproduce
Which of the following is NOT part of the founder effect
Some members of the group migrate
The new population can have a different allele frequency
Both the original population and new population survive
Can be caused by a natural disaster
Suppose wing span is a polygenetic trait. Those with both very large and very small wing spans do not survive. This is:
Disruptive selection
Stabilizing selection
Directional selection
Divergent selection
Which of the following IS NOT part of the Bottleneck Effect?
The new population can have a new allele frequency
The new population size decreases
Can be caused by a natural disaster
The populations are geographically separated
allele frequency
the number of a certain allele present in a population
the act of leaving one's own territory to settle permanently in another
the exchange of genetic material between homologous chromosomes during meiosis
the action of coming to live permanently in a new territory
crossing over
the number of a certain allele present in a population
the act of leaving one's own territory to settle permanently in another
the exchange of genetic material between homologous chromosomes during meiosis
the action of coming to live permanently in a new territory
gene pool
the collective alleles of all members of a population
the exchange of alleles between populations by immigration and emigration
changes of allele frequencies in a gene pool due to random/chance events
cell division which forms gametes
gene flow
the collective alleles of all members of a population
the exchange of alleles between populations by immigration and emigration
changes of allele frequencies in a gene pool due to random/chance events
cell division which forms gametes
genetic drift
the collective alleles of all members of a population
the exchange of alleles between populations by immigration and emigration
changes of allele frequencies in a gene pool due to random/chance events
cell division which forms gametes
mutation
random and irreversible changes in the DNA of an organism
the individuals in a population that are best suited to the environment and will leave more offspring than those which are not
mating which is the result of certain individuals selecting a mate based on phenotype
the differences in the genetic makeup of organisms within a gene pool
variation
random and irreversible changes in the DNA of an organism
the individuals in a population that are best suited to the environment and will leave more offspring than those which are not
mating which is the result of certain individuals selecting a mate based on phenotype
the differences in the genetic makeup of organisms within a gene pool
Genetic equilibrium in a population refers to ..
constant allele frequencies in successive generations
constant mutation rate in the population
equal numbers of dominant and recessive alleles
equal numbers of males and females
In a population of 1000 dragonfly, 80% alleles are dominant. What is the frequency of recessive allele?
0.8
0.2
20%
80%
