AP Biology: Unit 6 Test Review

The main goal of the Human Genome Project was to 

• identify the unique parts of each person's DNA
• identify genes responsible for human disease
• determine the entire sequence of human DNA.
• identify the structure of the DNA molecule

The specialized field of studying whole genomes, including genes and their functions, is called

• genomics
• bioinformatics
• the Human Genome Project
• information science

Which best describes the impact that the Human Genome Project has has on society?

• It has helped scientists determine that certain genes can cause diseases 
• It has led to discrimination against genetically flawed individuals
• It has led to the appearance of new diseases
• It has cost society billions of dollars without any major benefits

What is a genome?

• The complete set of genetic material present in a cell or organism
• A garden ornament 
• The sum of all human material.
• A totally unique set of genetic material not shared with anything else

Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)

• gene flow
• gene pool
• allele

The condition in which there are barriers to successful interbreeding between individuals of different species in the same community is referred to as 

• sexual dependency
• reproductive isolation
• geographic isolation
• adaptive radiation

The differences in sparrow songs among sympatric species of sparrows are examples of

• geographic isolation
• convergent evolution
• behavioral isolation
• mechanical isolation

NGSS.HS-LS2-8

Two allopatric species of sparrows have very similar niches when compared to two sympatric species of sparrows.  What would be a good explanation for this?

• The allopatric species have no competition with one another so therefore can occupy similar niches
• The sympatric species are usually mechanically isolated from one another
• The sympatric species diverged from a common ancestor
• The allopatric species are behaviorally isolated from one another
