Question

s there a sentence fragment?
When scientists sequenced the DNA of domestic cats, they made a startling discovery. A remarkable similarity between the genomes of house cats and those of their feline relatives in the wild.

Answer 1

Yes, there is a sentence fragment in your text. The second sentence, "A remarkable similarity between the genomes of house cats and those of their feline relatives in the wild," is a fragment because it lacks a subject and a verb to make it a complete sentence. You could combine it with the first sentence or revise it to form a complete sentence. For example, you could say: "They found a remarkable similarity between the genomes of house cats and those of their feline relatives in the wild."
