"This one here is your DNA. This one is Steven's DNA. You see how they're almost identical but there are minor differences?" He pointed to one of the differences. "This right here? No more arrythmia. And this one?" He pointed to another. "You can see color now. Height, muscle mass..." He pointed to some other changes. "But they're very minor. For the most part, they're the same."
He then pulled up two more profiles. "These here, are Banner and Mina. You know he's her father, right? And you can see there are some places where they're the same but only like 13 of the loci are identical, the rest are different. That's because he's only half of her genetic code."
He then pulled up two more that were completely identical in every way. "The one on the left is yours. The one on the right belongs to the kid." He ran his fingers through his hair. "They're completely identical." He really hoped that Steve caught on to what he was saying.
