In humans, the color of the eyes was thought as a simple Mendelian trait however, it has been found that the color of the eye follows polygenic inheritance, that is, it is determined by multiple genes.
A set of 15 genes is responsible for the color of the eyes. Two genes out of these 15 are OCA2 and HERC2 which are present on chromosome 15.
Thus we can conclude that eye colour is polygenic trait which does not follow Mendelian genetics.

<span>The characteristic of a chronic illness is that it leaves a patient with a permanent disability which can be physical or mental. This disability affects the day-to-day life activities of the patient, preventing the patient from performing activities of daily life. The patient may need family support for performing daily activities. In an acute illness, the patient returns to a fully functional life after treatment; in chronic illness the patient may not be able to resume a normal life. The treatment is more effective in acute illness; patients with chronic illnesses are less likely to respond to treatments in later stages.</span>
