Matching; Within each of the section, match the letter of the term with its definition by placing the
letter of the term in the blank. All terms are used and used only once.
______ process by which two species evolve in response
to changes in each other
A) genetic equilibrium
______ pattern of evolution in which long stable periods are
interrupted by brief periods of more rapid change
B) punctuated equilibrium
C) genetic drift
______ process by which unrelated organisms independently evolve
similarities when adapting to similar environments
_____ Changes in allele frequency in a small population that are due
to random chance and don’t follow the laws of probability
D) adaptive radiation
E) convergent evolution
F) coevolution
______ process by which a single species or small group of species
evolves into several different forms that live in different ways; G) mutation
rapid growth in the diversity of a group of organisms.
______ A change in the DNA sequence caused by a mistake in DNA
replication or exposure to radiation or chemicals
_____ A situation in which the allele frequencies in a population
do not change and the population does not evolve

B) founder effect
C) relative frequency
_____ All the genes, including all the different alleles, in a population
D) polygenic trait
_____ The idea that allele frequency will remain constant unless
one or more factors cause those frequencies to change
_____ The number of times a certain allele occurs in a gene pool
compared to the number of times other alleles for that same
gene occur

subgroup of a population to a new place
E) Hardy-Weinberg principle
F) gene pool
_____ The effect of natural selection when individuals at one
end of the normal distribution curve have higher fitness
than individuals in the middle or at the other end of the curve
A) DISRUPTIVE
SELECTION

extreme ends of the normal distribution curve have higher
fitness than those near the center of the curve
B) STABILIZING
SELECTION
_____ The effect of natural selection when individuals near the
center of the normal curve of distribution have higher fitness
than those at the extreme ends of the population
C) DIRECTIONAL
