BIO 202 UPDATED ACTUAL EXAM
QUESTIONS AND CORRECT ANSWERS
COMPLETE STUDY GUIDE
●● Species
Answer: A group of similar organisms that can breed and produce fertile
offspring.
●● Population
Answer: group of individuals of the same species that live in the same
area
●● Variation
Answer: Any difference between individuals of the same species.
●● Fossils
Answer: The preserved remains or traces of organisms that once lived on
Earth.
●● Biogeography
Answer: study of the distribution of organisms around the world.
,●● Convergent Evolution
Answer: Process by which unrelated organisms independently evolve
similarities when adapting to similar environments.
●● Selective Breeding
Answer: the human practice of breeding animals or plants that have
certain desired traits.
●● Homology
Answer: similarity due to shared ancestry
●● Adaptive Radiation
Answer: An evolutionary pattern in which many species evolve from a
single ancestral species
●● Endemic
Answer: confined to a particular country or area
●● Vestigial Structure
Answer: remnant of a structure that may have had an important function
in a species' ancestors, but has no clear function in the modern species.
●● Allele
, Answer: An alternative form of a gene.
●● Mutation
Answer: A change in a gene or chromosome.
●● Vertical Evolution
Answer: A process in which species evolve from pre-existing species by
the accumulation of mutations.
●● Horizontal Gene Transfer
Answer: The transfer of genes from one genome to another through
mechanisms such as transposable elements, plasmid exchange, viral
activity, and perhaps fusions of different organisms.
●● Homologous Genes
Answer: two genes derived from the same ancestral gene
●● Gene Family
Answer: two or more different genes within a single species that are
homologous to each other because they were derived from the same
ancestral gene
●● Paralogs
