Distorted Gene Syndrome !!!

You have seen those pictures of white colored swiftlets.

According to many people the white color of the feathers are due to lack of black colored pigments. This might be due to many reasons but the most common is due to distortion of their gene.

Crows, which are usually black, also face the same pigmentation problem.

Have a good look at this picture and you can see that even their beak and feet are affected.

They term the phenomena as albino.
