CB 1.3 GENETIC VARIATION
GENETICS OF POPULATIONS
Define a 'population
bottleneck'. What
does a 'significant
reduction in
numbers' mean for
the genetic variation
of the takahē?
Take into account
the historical decline
of the takahē
population from
400 to 118 in 1982.
How would such a
reduction impact
the genetic variation
of the population?
Define the 'founder
effect' and link this
to relocating takahē
to offshore islands.
Consider what
limitations a new,
smaller population
might face if it is not
genetically diverse.
Reflect on
what measures
conservationists can
take to mitigate the
negative impacts of
the founder effect.
How important is it
to ensure that the
takahē selected
for relocation are
genetically diverse?
Hints for answering
these questions
