Some Evolutionary Biologists Argue That, Overall, Regulatory Mutations Are More

question 39

Multiple Choice

Some evolutionary biologists argue that, overall, regulatory mutations are more likely to result in adaptation than changes in the protein-coding sequence of genes. Considering the logic underlying their argument, in which case below would this expectation not apply to a particular gene involved in adaptation?

• A) The gene is involved in multiple functions.
• B) The gene is involved in only one function.
• C) The gene is expressed in different tissues.
• D) The protein encoded by the gene performs an important function.

The layer of igneous, sedimentary, and metamorphic rocks that forms the continents and the areas of shallow seabed close to their shores.

Felsic Composition

Rocks rich in silica and aluminum, characterized by lighter minerals like quartz and feldspar.

Decompression

Melting Mantle

The process in which the Earth's mantle, the layer between the crust and the core, experiences partial melting to form magma.
