BIO 202 EXAM 1 COMPREHENSIVE QUESTIONS
AND ANSWERS GRADED A+ PREPARATION
◉ 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.
