Baldness, Color Blindness, Lactose Intolerance, Acne and Heart Disease are traits which are genetic.

In an age when we do everything possible to be our best there are some things we just can’t change.
Colorblindness affects about 10 percent of men but less than 1 percent of women. It is directly inherited, and here’s why it’s more common in men: Genes for the eye’s red and green receptors sit near each other on the X-chromosome. Men have one X-chromosome, which they inherit from their mother; women have two, and a good gene will often balance out a defective one. Ninety-nine percent of cases involve the challenge of distinguishing between reds and greens. Complete colorblindness, or achromatopsia, is rare, affecting about one in 30,000 people worldwide. Interestingly, colorblind people dream in whatever colors they normally distinguish when awake.
