QUESTION 31
The ancestor to the Hawaiian crickets in the genus Laupala originally colonized the oldest of the island in the Hawaiian archipelago. As new islands were formed, individuals from the older island would colonize the younger island. Because members of this genus are flightless, these migration events were likely to be extremely rare and would include a small number of migrants. Differences in allele frequencies in this genus are likely due to:
population bottleneck.
founder event.
drift.
A and C.
B and C.
2 points
QUESTION 32
A founder event changes allele frequencies because:
only a subset of genes in the original population are observed in the founder population.
of random sampling of alleles from the original population.
of the coalescent process.
A and B.
All of the above.
2 points
QUESTION 33
The neutral theory of molecular variation posits that:
most mutations are neutral.
most substitutions are neutral.
most mutations are deleterious.
B and C.
All of the above.
2 points
QUESTION 34
The nearly neutral theory:
relaxes assumptions concerning the selective neutrality of alleles.
can be used to explain the discrepancy between substitution rates explained by generation time and annual time.
suggests that mildly deleterious mutations can fix more readily in smaller populations due to drift.
A and C.
All of the above.
a.population bottleneck.
b.founder event.
c.drift.
d.A and C.
e.B and C.
