CSUF BIO 152 EXAM 1 WITH
CORRECT ANSWERS 2025
Homologous correct answers >> A trait that is inherited from
a common ancestor
Analogous correct answers >> A trait that performs the same
function in highly unrelated species
Synapomorphy correct answers >> A shared derived trait
Symplesiomorphy correct answers >> A homologous
ancestral trait (shared characteristic that has evolved much
earlier)
Autapomorphy correct answers >> A unique derived trait
found only in a tip lineage
Convergent correct answers >> A trait that has evolved
independently multiple times on a phylogeny
Monophyletic Group correct answers >> An ancestor and all
of its descendants
Node correct answers >> Part of a phylogeny where
speciation has occurred
, Polytomy correct answers >> Part of a phylogeny showing
uncertainty in evolutionary relationships
Paraphyletic Group correct answers >> An ancestor and
some but not all of its descendants
Evolution and Natural Selection refer to the same process
correct answers >> False
Genetic drift acts to increase genetic variation within a population
correct answers >> False
Mutation is a completely random process correct answers >>
True
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 resulting
from the reduction of a population, typically by a natural disaster,
such that the surviving population is no longer genetically
representative of the original population.
The founder effect is an example of gene flow correct answers
>> False
