Matching
Match the evolutionary concepts correctly with the correct description or example. Some choices may be used more than once.
Premises:
Large antlers are energetically costly and may get stuck on branches, but females prefer to mate with bucks with the largest antlers.
The Industrial Revolution resulted in soot-covered trees, which allowed dark-colored peppered moths to blend in and escape predators; the moth population eventually became comprised of mostly dark-colored individuals.
The genitals of snakes are analogous to a lock and key mechanism-the "keys" will only fit in certain "locks."
Animals that have too few offspring risk that all of them will be lost to predators, and therefore, their genes will not be passed onto the next generation. Animals with too many offspring may not be able to take care of all of them. Therefore, most animals have an intermediate number of offspring.
The migration of bison from one herd to another results in this.
A small population of humans colonize a deserted island and most of them have attached earlobes. One hundred years later, the colony consists of 550 people, all of whom have attached earlobes.
Two species of hawk are able to mate successfully, but one hunts in the morning and the other hunts at night. Mating between the two species, therefore, does not occur.
A change in allele frequencies in a population that does not result from adaptation or natural selection.
Homozygous dominant black mice are camouflaged by dark rocks, and homozygous recessive light-colored mice are camouflaged by light-colored rocks. Heterozygous grey mice have no camouflage and are easily picked off and eaten by hawks.
Prairie grouse females choose to mate with males that display the most intricate dance and make the loudest thumping noise with their chests.
Responses:
genetic drift
stabilizing selection
disruptive selection
