test 3 part 4

Question 1

what is the founder effect?

Answer 1

a few individuals from a population start a new population

Question 2

what is gene flow?

Answer 2

individuals moving from one population to another

Question 3

what is a population bottleneck?

Answer 3

the reduction of population size by an event.

Question 4

the rapid loss of individuals leads to random change in what?

Answer 4

the genetic constitution of the surviving populoation

Question 5

bottleneck typically follows what?

Answer 5

a large-scale mortality event or lage reproductive reduction

Question 6

what is a wide bottleneck?

Answer 6

more alleles survive (and typically organsims)

Question 7

what is a tight bottleneck?

Answer 7

less alleles survive (and typically organsims

Question 8

what is the hardy weinburg idea?

Answer 8

allele and genotype frequencies tend to remain constant in the abscence of disturbing forces.

Question 9

hardy weinburg is what int he equation for figuring out evolution?

Answer 9

the null hypothesis

Question 10

if the populations are in HWE then the genotype frequancies should be what?

Answer 10

predicatble based on allele frequencies

Question 11

if there is genetic drift typically that means what for the population?

Answer 11

the population size is small
