Eye Color

Contact lenses are tinted for cosmetic reasons, ie, to modify or change eye color, and for visibility, ie, to locate the lens mote easily when it is out of the eye. 

The color of die iris may change because of an increase of the brown pigment and cause different eye coloration. This may be more noticeable in patients with blue, green, or gray brown or other light-colored eyes. 

Phenotype The expression of the genes present in an individual. This may be directly observable (e.g., eye color) or apparent only...

Modern biotechnology, defined as the movement and modification of genes at will, was built on discoveries in genetics and biochemistry originally made in the first half of the 20 century. Scientists learned that inherited characteristics or traits, such as hair or eye color, are passed from parents to offspring in units of inheritance called genes. You may have learned how an Austrian monk named...

Alleles One of two or more alternate forms of a gene occurring at the same position on a chromosome. A gene for eye color, for example, may exist in two allelic forms, one for blue and one for brown.
