Speciation Fill In Notes

"Temporal" = relating to time
2. Temporal Isolation
__________________________ occurs when two populations reproduce at
different __________________.
Ex. There are 4 groups of Chinook salmon who spawn at different times of the
year along California's central coast: winter, spring, summer and fall. The
populations who breed in one __________________ never breed with those in
another ______________.
3. Behavioral Isolation
_________________________________ occurs when two populations have differences
in ____________________rituals or ____________________ that prevent them from
interbreeding.
Example: eastern and western meadowlarks will not mate with each other
because they use different _________________to attract mates.
Ex. Two species of tree frogs that live side-by-side in the southeastern U.S.
have different ___________________________.
How does isolation lead to speciation
Organisms that are isolated respond differently to _____________________________
and have different ________________________________.
They could ___________________ to become so _________________different
that they can no longer breed and produce fertile offspring.
So, even if they were brought together in a zoo, they still couldn't have fertile
offspring.
Ex. Their chromosomes cannot form homologues in meiosis.
