While it may limit prospects for certain jobs, most people<br>find ways to adapt to the condition. Colour vision defect is usually for red-green colour and it is X-linked<br>recessive trait. It is mainly homozygous that develop colour vision defects. Female heterozygous usually<br>have normal vision. Colour vision defects also have a strong genetic component , especially if both parents<br>have colour vision defects , and people with a particular blood group , and very myopic or hypermetropic<br>, there is a good chance their child will be same. Color blindness is often apparent at a young age when<br>children are learning their colours and goes undetected because as they grow they learn to associate specific<br>colours with certain objects.For example, they come to know that grass is green, so they call the colour they<br>see green. If symptoms are very mild, a person may not realize that they don’t see certain colours.</p> ER -
