A population of mice with light tan color fur live in a shady
forest. Then a mutation results in some mice with a dark brown
coloration. The darker mice are harder for predators to see in
the leaf litter, thus they are less likely to be eaten. After 10
generations, the majority of mice in the population are dark
brown. In the figure above, the solid line represents the number
of light colored individuals before the mutation and the dashed
line represents the number of dark brown individuals after 10
generations. What type of natural selection are the population
of mice going through? - ANSWER -Directional selection
Migration between two populations is referred to as - ANSWER -
gene flow
What mechanism leads to changes in allele frequencies
due to random
chance? - ANSWER -
Genetic drift
, Which of the following would most likely result in a bottleneck
event? - ANSWER -A hurricane blows through a coastal swamp
inhabited by an apple snail population. The hurricane
drastically changes the hydrology of the swamp, killing 98% of
the apple snails.
People are sent to colonize a planet many light years away from
earth. This mission is successful, but the rapidly growing
population has a higher than normal percentage of people with
genetic diseases. What is probably the reason for this? -
ANSWER -Founder effect
The process of evolutionary changes that result in formation of
new species is -
ANSWER –
macroevolution
A group of individuals that can interbreed in nature and produce
viable offspring
would be considered to be a species according to the
____________________
concept - ANSWER -biological
species
The Northern leopard frog (Rana pipiens) and Southern
leopard frog (Rana
utricularia) are morphologically similar, but their mating
calls sound very
