The Rehpogs in the original population that stayed in the warm environment has maintained their original
genetic diversity of 50% dominant alleles for thick purple fur and 50% recessive alleles for thin pink fur.
Remember that the original population of Rehpogs lived on the ground in a relatively flat habitat. This
group is called Population A.
The population has increased to where there is not enough food for everyone. About half of this
genetically diverse group of Rehpogs (Population B) was sent out by the leader to find a suitable new
home in the uneven, rocky territory to the south. Population A stayed behind in the flat habitat.
Unfortunately, an unexpected effect of the dominant allele for thick purple fur is vertigo. None of the
Rehpogs noticed this associated trait before they moved to the uneven, rocky territory because these little
creatures do not get hurt if they fall over on level ground.
Sadly, when the thick purple furred Rehpogs walk on pathways in the uneven, rocky territory, they tend
to fall off cliffs and die. The uneven, rocky environment exerts selective pressure. Field studies show
that up to 50% of the homozygous dominant individuals in the uneven, rocky territory population die
from falling off cliffs every year.
Which group (Population A that stayed in the flat territory or Population B that moved to the
rocky territory) will change dominant allele frequency more quickly than the other?
