ANSWERS) /ALREADY GRADED A+



What is Artificial Selection? - ....ANSWER...-
Selecting individuals to breed can result in dramatic
modifications over generations


What force in evolution can be used as evidence of
natural selection? - ....ANSWER...Artificial Selection,
Camouflage, Biogeography, Homologous structures


What is Biogeography? - ....ANSWER...- Unrelated
organisms evolved similar adaptive solutions to the
same problem
Ex: Ostrick, Emu


-Related organisms tend to be found in the same
geographic area

,What is Homologous Structures? -
....ANSWER...Similar parts in various organisms
ex: the forelimbs of all mammals contrasted from
the same skeletal elements
Human, Cat, Whale, Bat


1. Individuals in a population vary phenotypically
2. Some variants fit better into their (current)
environment than others
3. Those variants produce more offspring
4. If there is genetic basis to the variation ....then
5. Those alleles will increase in the population over
time - ....ANSWER...Evolution


1. Selection acts ONLY if the trait has a genetic basis
2. Selection acts ONLY if there is variation present
3. Selection does NOT CREATE new genes or alleles,
nor does it create variation
4. Selection DOES produce... -
....ANSWER...Adaptation

,What is Adaptation? - ....ANSWER...The evolutionary
process whereby an organism becomes better able
to live in its habitat


How would Genetic Diversity come about? -
....ANSWER...If there were many loci and additive
effects


What is Directional Selection?


Ex: Mice
Colonized a place where there was light soil and
dark rocks? - ....ANSWER...- Moves the average
phenotype in one direction or the other, depending
on what the actual effect is
- Genetic variation is reduced


Only light and dark mice would survive, medium
would be picked off


What is Disruptive Selection?


Ex: Mice

, What if the medium colored mice continued to blend
best with the environment - ....ANSWER...- Selection
favors variants at each extreme
- Genetic variation is increased


Medium-colored mice population would increase


What is Stabilizing selection? - ....ANSWER...- Over
generations there will be fewer light and dark
colored mice
- But the average stays the same
- Stabilizing selection removes extreme variants
from the population
- Reduces phenotypic variation
- Genetic variation is reduced


What is Balancing selection? - ....ANSWER...- No
single phenotype is favored in all populations of a
species at all times
- Genetic variation is maintained


What is gene flow? - ....ANSWER...- Migration of
individuals between populations
