24.
Gene flow occurs...
a)
...when natural forces act on existing variation
b)
...when two populations mix, but do not mate
c)
...when new individuals are added to a population
d)
...when a population is split
25.

Genetic changes only occur in populations

Populations do not necessarily consist of the individuals best adapted to survive and reproduce. Theoretically, the most fit individuals in a population will survive longest and reproduce the most, however chance plays a role in who survives, Reproduces, and whose offsprings survive to reproduce as well. In a population, where the allele frequency shifts by random chance, the mechanism of evolution at work is___.
a)
Natural selection
b)
Genetic drift
c)
Migration
d)
Mutation
27.

so that their babies can have friends to play with
b)
the more offspring the more likely the offspring will survive
c)
the more offspring the less likely offspring will survive
d)
the more offspring the less competition

Why would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment?
a)
Individuals will only create offspring well-suited to the climate change
b)
The individuals would produce more offspring
c)
Individuals better suited to the new climate will help less-suited individuals survive
d)
Some individuals will posses traits better suited to the new climate and be more likely to pass them on
