Question
This effect shifts a site frequency spectrum to the right by making rare mutations more common. For 10 points each:
[10m] Name this effect, a form of genetic drift in which a non-representative sample of individuals is geographically isolated from a group.
ANSWER: founder effect [reject “speciation” or “allopatric speciation”]
[10e] Founder effects suppress the “effective” form of this quantity, which is a metric of genetic diversity. Carrying capacity is a limit on this value.
ANSWER: population size [prompt on size; prompt on N; prompt on number of individuals]
[10h] The effective population size is the fraction of a population with this property over four times the mutation rate. In a population with complementary gene frequencies p, q, and r, the expected frequency of this property is [read slowly] “1 minus p squared minus q squared minus r squared.”
ANSWER: heterozygous [or heterozygosity; prompt on H]
