Babies might look more like one parent if they inherit more dominant traits from that parent. It’s like mom’s or dad’s features shining through more brightly.

Question 16

Accepted Answer

Scientists study genetics by looking at DNA samples and studying how genes work. They use special tools to zoom in on the tiny parts we can't see with our eyes.

Question 17

Can children inherit talents from their parents?

Accepted Answer

Children can inherit certain abilities, like a good sense of music, but practice also plays a big part in developing talents. It’s a bit of nature and nurture working together.
