Answer 1

All the options provided are examples of traits that DNA can code for. Here’s a brief explanation of each:

A. **Risk for certain diseases** - Certain genetic variations can increase the likelihood of developing specific diseases, thereby influencing an individual's health risk profile.

B. **Height** - Height is a polygenic trait, meaning it is influenced by multiple genes as well as environmental factors.

C. **Eye color** - Eye color is determined by several genes that affect the pigmentation of the iris, making it another trait coded by DNA.

D. **Hair color** - Like eye color, hair color is influenced by multiple genes that determine the type and amount of melanin produced.

In summary, DNA codes for all these traits.
