DNA contains equal amounts of adenine/thymine and guanine/cytosine.
Answer:
The sequence data that would support this hypothesis would involve there being relatively more differences found between the three mitochondrial genes' sequences of the La Plata River dolphin and the sequences of the Chinese River dolphin.
There should also be fewer differences between the three mitochondrial genes' sequences of the La Plata River dolphin and the sequences of the Amazon River Dolphin.
Explanation:
This is because fewer differences between the mitochondrial gene sequences of two species indicate closer relatedness and more differences indicate lower relatedness.
