Directional Selection...
chooses the extreme allele of the trait
chooses the the medium/average trait
chooses half the population to be light and the other half to be dark; both extremes are chosen
is a theory that evolution occurs at a slow rate
the theory that states evolution happens when there is an event in life that affects organisms on a large scale. evolution happens quickly at this point.
gradualism
disruptive selection
punctuated equilibrium
normalizing
this type of selection chooses half of the population for one extreme and chooses the other half to be the other extreme; both extremes are chosen
stabilizing selection
gradualism
punctuated equilibrium
disruptive selection
this graph represents what selection?
stabilizing
directional
disruptive
this theory states evolution happens at a slow rate...
stabilizing
disrupting
processing
gradualism
stabilizing selection is...
the type of selection that chooses the extreme allele of the trait
the type of selection that chooses the medium/average trait
the type of selection that chooses half the population for one extreme and one half for the other
when evolution happens at a slow rate
what type of natural selection is this?
disruptive
directional
stabilizing
this is an example of what type of natural selection
directional
disruptive
stabilizing
what is an example of directional selection?
population will develop medium fur in the next generation
population will develop dark fur in the next generation
population will develop both light and dark fur in the next generation
what is an example of disruptive selection?
population will develop medium fur in the next generation
population will develop dark fun in the next generation
population will develop both light and dark fur next generation
why is punctuated equilibrium not referred to as quick evolution?
an event in life must affect an organism on a large scale before it can happen quick
the evolution occurs slowly
the evolution happens at a steady rate
why is gradualism simply known as evolution at a slow rate
because it simply states that it happens at a slow rate
its not, it happens quickly
it can also happen at a fast rate
