• Bold and uppercase

• Italicized and lowercase

What is the primary basis for grouping organisms in taxonomic ranks?

According to the biological species concept, what is a key feature of a species?

• Ability to live in water

• Ability to interbreed and produce fertile offspring

• Ability to fly

• Ability to photosynthesize

What is required for members of a species to interbreed?

• Different genetic profiles

• Compatible genetic profile

• Different chromosome numbers

• Incompatible genetic profile

What is karyotyping?

• The process of sequencing DNA

• The process of pairing and ordering chromosomes

• The process of creating genetic mutations

• The process of cloning organisms

What is a genome?

• Only the nuclear DNA of an organism

• All genetic information within an organism

• Only the organelle DNA of an organism

• Only the RNA of an organism

What does whole genome sequencing determine?

• The sequence of a single gene

• The sequence of an entire genome

• The sequence of only the nuclear DNA

• The sequence of only the organelle DNA

What is the relationship between organism complexity and genome size?

• Larger genomes always mean more complex organisms

• Smaller genomes always mean less complex organisms

• There is no clear correlation

• Larger genomes always mean less complex organisms
