What is albinos?

@Anitha.

Albino means pure white. They have no melanin pigment for their skin. And it is controlled by 3 pairs of recessive genes (polygene).

More the amount of melanin in our body, More than and darker look and it is more interesting to know that the secretion of this pigment increases with our exposure to sunlight. That is why we usually change to a shade darker after dealing with sunlight.

Flavoxathin is a natural xanthophyll pigment with a golden-yellow color found in small quantities in a variety of plants.

Melanin is a harmone which present in our skin is responsible for this process.

Melanin helps us to protect from harmful rays. You will see people around equator are dark as rays are more there but in areas around poles have light sunlight and skin tone is light because of melanin.
