Answer:
Reproductive isolation occurs faster in deep-water shrimp than shallow-water shrimp.
Explanation:
Though in the same territory, the blockage caused by the isthmus would quickly and permanently isolate shrimps living in the deeper parts of the water, thus making them unable to breed. This situation would then caused lack of gene flow within the deep-water shrimps , and the emergence of new species that are genetically different (diverge) from one another
The shallow-water shrimp, on the other hand, experience minimal isolation due to the shallowness of water, and could still breed with one another. Thus, they experience a relatively lower reproductive isolation

Answer:
The correct option is <em>C. A gene is a specific segment of DNA on a chromosome</em>

Option A is false because a gene is a segment on a chromosome.
Option B is false because a chromosome carries many genes.
Option D is false because a gene carries a segment of DNA, not all of the DNA.
Option C is correct because there are many genes present on a single chromosome. Each gene carries a segment of DNA. The position of a gene on the chromosome is known as its loci.
