BIO 121 Final Exam Questions With
Accurate Answers 100% Correct
Passing of traits from parents to offspring - correct answers What does Descent with Modification
mean?
Change over time - correct answers What is evolution?
genetic mutations that are beneficial to an individual's survival are passed on through reproduction -
correct answers How are genes involved in natural selection?
Charles Darwin - correct answers Who contributed to the main ideas of how diversity arose?
members of the population vary in their inherited traits & all species can produce more offspring than
the environment can support, but many fail to survive and reproduce - correct answers What were the
initial observations and inferences that led to natural selection?
any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its
environment - correct answers What is adaptation?
whether reproductive success is driven by naturally occurring processes, or whether the selection is
imposed by humans - correct answers How is natural selection different from artificial selection?
Natural: Long-Necked Giraffes
Artificial: Breeding of different varieties of dogs or cattle to produce the desired varieties - correct
answers Example of Natural and Artificial Selection
similarity resulting from common ancestry - correct answers What is homology?
, unrelated species evolve similar traits even though they live in different parts of the world - correct
answers What is convergent evolution?
species found in one place and nowhere else - correct answers What is an endemic species?
population - correct answers What is the smallest unit of evolution?
All the organisms of one species living in a habitat - correct answers What is a population?
Change in allele frequencies in a population over generations. - correct answers What is microevolution?
Natural selection, Genetic Drift, Gene Flow - correct answers What are the 3 mechanisms that cause
changes in allele frequency?
all the genes in a population - correct answers What is a gene pool?
counting how many times the allele appears in the population then dividing by the total number of
copies of the gene - correct answers How do you calculate the frequency of an allele in a diploid
population?
the number of homozygous and heterozygous variant carriers based on its allele frequency in
populations that are not evolving - correct answers What is Hardy-Weinberg Equilibrium used to
measure?
- No Mutation
- Random Mating
- No Natural Selection
- Extremely Large Population Size
- No Gene Flow - correct answers What are the 5 conditions for H-W Equilibrium?
p² + 2pq + q² = 1 - correct answers What is the equation used in H-W Equilibrium?
