(I underlined the chromosome regions that become inverted to give rise to the next species)
<h3>1st sequence ST<u>UVWX</u></h3><h3>3rd sequence S<u>TXWV</u>U</h3><h3>2nd sequence <u>SVWX</u>TU </h3><h3>4th sequence XWVSTU </h3>

Answer:
2. comparative morphology
Explanation:
- Morphology is the study of the structure as well as the form of the organisms and studying their specific features.
- When the morphological characters of two or more different organisms are compared usually for the bass of taxonomical characterization then this is termed as comparative morphology.
- Using comparative morphology both similarities and differences in the anatomical structures of the organisms are observed.
- Using the comparative morphological studies one can see the common descent as well as the divergence of organisms.
- Therefore, Dr. Wilson is using comparative morphology to study similarities between the wing of a bat and the arm of a monkey.

</span>Speleology is shortly defined as the<span> scientific study of caves.</span> Speleothems are structures<span> formed in a cave by the deposits of minerals from water dripping from the fractures of the ceiling of the cave. Most common types are the stalactites and stalagmites. </span>
<span>Stalactites began as a ring of crystals which later becomes small tubes with a hollow center.</span><span> Stalagmites, on the other hand, are tubes formed without hollow centers. </span>
