Microevolution Quiz

when does gene flow occur

• by having offspring

• when individuals join new populations and reproduce

• when organisms reproduce

The founding of a small populations can lead to

• genetic drift

• populations

• offspring

• isolations

Genetic drift causes a loss of

• genetic diversity

• populations

• isolations

• offspring

A gene pool is

• all of the alleles in an individual

• all of the alleles in a population

• a body of water filled with fish

• all of the bases in one strand of DNA

Those individuals in a population better equipped to survive will produce more offspring

• genetic creation

• offspring destruction

• bottle neck effect

• natural selection

The formation of new species due to evolution

• creation

• mutation

• elimination

• speciation

Microevolution is small changes to the genes of a population involving all but one of the following:

• genetic drif

• gene flow

• non random mating

• no mutation

• natural selection

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

• gene pool 
• founder effect
• bottleneck
• mutation

Ten years ago, in a small population of ducks, two sizes of eyes were observed, large and small. Three ducks have large eyes and 7 have small.  2 of the large-eyed ducks are randomly hit by cars and killed. Today, no large-eyed ducks are present in the population.

• gene flow
• bottleneck
• mutation
• founders

The more genetic variation a population has,

the more likely it is for some individuals to

• evolve

• migrate

• survive

• mutate
