BSC 101 Final Exam Wodika UPDATED
QUESTIONS AND CORRECT ANSWERS
Mutation - CORRECT ANSWER Change in DNA sequence from mutagens or an error in DNA
replication. (All genetic variation arose from genetic mutations.)
Genetic Drift - CORRECT ANSWER Changes in gene pools due to randomness or chance
events; (by change only brown rabbits are reporudced instead of white ones.)
Gene Flow - CORRECT ANSWER Movements of alleles between populators; migration, seed,
or pollen (gametes)
Allele Frequencies - CORRECT ANSWER Frequency of an allele in a population that has
nothing to do with it being dominant or recessive.
Allopatric Speciation - CORRECT ANSWER Populations become graphically separated, gene
flow is interpreted, genetic and phenotypic changes accumulate, and reproduction becomes less and
less likely than eventually impossible.
Sympatric Speciation - CORRECT ANSWER Formation of a new species in a population that
lives in the same geographic area.
Phylogenies - CORRECT ANSWER Most recent common ancestor (nodes)
Evidence Supporting Evolutional Theory - CORRECT ANSWER 1. Fossil evidence
2. Morphological Homology
3: Molecular Homology
4:Distribution of organisms/fossils in time and space
5: Chronology
Evolution - CORRECT ANSWER Not a theory
