A company trains dolphins to be gentle enough to swim with people. The company prefers female dolphins and can use biotechnology to be sure that female dolphins are born during breeding. This gender-selection technology would be almost identical in humans. Why is this technology most likely not available to people?

Therefore, the correct choice is “The technology has ethical concerns.”
