Accepted Answer

A)  100 percent
B)  80 percent
C)  25 percent
D)  0 percent
E)  impossible to determine

Question 5

Migration refers to:

Accepted Answer

A)  a long-term movement to a new area
B)  movement to a new area,including a short trip
C)  a high death rate due to natural selection in new areas
D)  rapid evolutionary change

Question 6

Genetic equilibrium is maintained in a gene pool under ideal conditions.This equilibrium is disturbed by:

Accepted Answer

A)  gene flow
B)  random mating
C)  lack of natural selection
D)  all of the above

Question 7

If allele A has a frequency of 0.70 and allele a has a frequency of 0.30,then the frequency of the heterozygote genotype would be:

Accepted Answer

A)  0.42
B)  0.36
C)  0.21

Question 8

In tribal societies trust is placed with family members as opposed to those outside the family.This extends to marriage,where the most desirable marriages are with relatives.In one society on the northwest coast of British Columbia the most desirable marriage is between a boy and his mother's brother's daughter,which makes his mother's brother (maternal uncle) his father-in-law.This type of mating is called:

Accepted Answer

A)  assortative mating
B)  incest
C)  consanguineous mating
D)  random mating

Question 9

The probability is that a genetic disease with the highest carrier rate among members of group A will occur:

Accepted Answer

A)  at the lowest rate if members of group A mate only with other members of group A
B)  at a lower rate if members of group A mate outside of the group as opposed to mating within it
C)  at a higher rate if members of group A mate outside of the group as opposed to mating within it
D)  at about the same rate as any other group,since carrier rates do not directly affect resultant phenotypes

Question 10

Mutations caused by human-made substances or activities are:

Accepted Answer

A)  spontaneous mutations
B)  induced mutations
C)  of no evolutionary significance
D)  all of the above

Question 11

If a population of early humans was reduced from 50,000 to 500 individuals because of a natural disaster,we might find that the resulting and future populations show,when compared with the original population:

Accepted Answer

A)  no changes in gene frequencies
B)  greater genotypic and phenotypic variation
C)  less genotypic and phenotypic variation
D)  further reduction in population size leading to extinction

Question 12

Not all matings are equally fertile.This is part of:

Accepted Answer

A)  genetic equilibrium
B)  genetic drift
C)  genetic load
D)  natural selection
