Bison have come close to extinction due to uncontrolled hunting, drought, and
disease. There is now very
little
genetic variation in bison
populations.
Which of the following is a result of the
limited genetic variation in the
current bison populations compared
to earlier bison populations with
more variation?
Select one:
O a. Bison in current populations are more resistant to new
diseases.
O b. The survival rate of young bison has increased in current
populations
O c. Bison in current populations are less able to interbreed with
other species
O d. The current bison populations are less likely to be able to
adapt to environmental changes.
