BIOLOGY 152 EXAM WITH
CORRECT ANSWERS 2025
Adaptation correct answers >> Inherited characteristic of an
organism that enhances its survival and reproduction in specific
environments
Natural selection correct answers >> A process in which
organisms with certain inherited characteristics are more likely to
survive and reproduce than are organisms with other
characteristics.
Artificial selection correct answers >> The selective breeding
of domesticated plants and animals to encourage the occurrence
of desirable traits
Observations of change, fossil record, homology, biogeography
correct answers >> 4 Supporting Lines of evidence for Evolution
Analogy correct answers >> The similarity of two species due
to convergent evolution. These species have similar
characteristics because they live in similar environments
Homology correct answers >> Similarity in shared
characteristics because of shared common ancestry
Population correct answers >> What is the smallest
biological unit evolution can affect?
, Mutation correct answers >> What is the ultimate source for
new alleles?
Allele correct answers >> Any alternative forms of a gene
that produce distinguishable phenotypic effects
Gene pool correct answers >> The aggregate of all alleles
from one population to another, resulting from the movement of
fertile individuals or their gametes
No natural selection, no mutation, no genetic drift, no gene flow,
random mating correct answers >> What are the conditions
of Hardy Weinberg's equation?
Founder effect correct answers >> Genetic drift that occurs
when a few individuals become isolated from a larger population
and form a new population whose gene pool composition is not
reflective of that of the original population
Bottleneck effect correct answers >> Genetic drift that
occurs when the size of a population is reduced by natural
disaster or human actions. Typically, the surviving population is
no longer genetically representative of the original population.
Relative fitness correct answers >> The contribution and
individual makes to the gene pool of the next generation, relative
due to the contributions of other individuals
