BIO 132- EXAM 2 QUESTIONS WITH
VERIFIED ANSWERS A+ PASS
What is homology? - Answer- Similarity due to common ancestry.
What does the genome contain? - Answer- The complete set of genetic instructions
(DNA) in an organism.
What is genomics? - Answer- The study of entire sets of genes and how they interact.
What was the goal of the Human Genome Project? - Answer- To sequence the entire
human genome.
What is the first step in genome sequencing? - Answer- Cut DNA into overlapping
fragments.
What is Whole Genome Shotgun Sequencing? - Answer- A method that randomly
breaks DNA and sequences small fragments, allowing for faster assembly.
What are exons? - Answer- Coding regions of DNA that are expressed.
What are introns? - Answer- Noncoding regions of DNA that are removed before
translation.
What are transposable elements? - Answer- DNA sequences that can move within the
genome and cause mutations.
What is microevolution? - Answer- Change in allele frequencies within a population over
time.
What is natural selection? - Answer- The process where the environment 'chooses'
which traits survive based on existing variation.
What is the Biological Species Concept? - Answer- Defines species as populations that
can interbreed and produce fertile offspring.
What is allopatric speciation? - Answer- Speciation that occurs due to geographic
separation.
What is sympatric speciation? - Answer- Speciation that occurs without geographic
barriers, often due to habitat differentiation or sexual selection.
What is a hybrid zone? - Answer- A region where two species mate, leading to possible
reinforcement, fusion, or stability of hybrids.
