Answer 2

Step-by-step explanation:

1. Lighter colored eyes like blue, hazel and green

2. Lighter colored eyes like blue, hazel and green have less of a pigment called 'melanin' than brown eyes do. Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.

3. Natural red hair

4. Natural red hair is the rarest hair color in the world, only occurring in 1 to 2% of the global population. Since red hair is a recessive genetic trait, it is necessary for both parents to carry the gene, whether or not they themselves are redheaded. Due to this there are more people who carry the redhead gene, than there are people with red hair.
