Question 4: (10
pts) In southwest Arizona there is a large, isolated population of kangaroo
rats with over 1000 individuals and a 50:50 sex ratio. You genotype these kangaroo
rats at 10 SNPs. You start this genotyping project in the year 2020. In year
2050, the population undergoes a large population decline to 10 individuals and
stays around 10 individuals until the year 2100, at which point you retire (at
a very old age). Draw a plot illustrating the allele frequencies of all 10 loci
from year 2020 to year 2100. Label all axes clearly!
Now draw a second plot similar to that in the question
above, except that in the year 2050 the population does not decline, but
instead responds to a new selective pressure in the form of a novel disease
spreading into the population. The disease is a strong agent of selection and
results in considerable mortality. Importantly, 5 of the loci are neutral and
the other 5 are linked to genes that play a role in disease resistance. Explain
your plots.
