(K) Ryan was sitting in class when he noticed that his friends all had different hair colors. Some had blonde hair, Ayushman had black hair, and DiDonato had brown hair, like him. Curious, Ryan asked his teacher why everyone’s hair was different. His teacher explained that hair color is determined by DNA, which we inherit from our parents. Ryan started wondering: If DNA decides hair color, does it also decide what his favorite food is?
No, it doesn’t. Ryan’s favorite food would be determined by his experiences, like places he’s been. For example, Mexico, Italy, and China.

(E) Adriana sat in the cafeteria, looking around at her classmates. She noticed that some of them could roll their tongues into a tube, while others couldn’t. She tried it herself—and it worked! Her friend Juliaanki, sitting next to her, tried but couldn’t do it. “How come you can do that, but I can’t?” he asked. Adriana thought about it for a moment. She remembered reading that some traits, like tongue rolling, are linked to DNA. But then she wondered—if it’s in our DNA, does that mean everyone in her family can do it too? Or could some family members have different abilities? What do you think?
Some people in Adriana’s family may be able to roll their tongue, but all of them may not be able to. This ability is influenced by DNA, but it may not be a dominant trait. Therefore, some family members could have different abilities.

(H) Vivaan was curious why he had brown eyes, but his brother had green eyes. Help him figure it out! (No, he’s not adopted.)
